    (lp#767959)
  * bug fix: compiling calls to eg. MEMBER with massive constant list arguments
    could exhaust stack.

changes in sbcl-1.0.47 relative to sbcl-1.0.46:
  * bug fix: fix mach port rights leaks in mach exception handling code on
    darwin/x86 and /x86-64. (thanks to Willem Oudshoorn for motivation and the
    initial patch)

  * enhancement: redefinition warnings for macros from different files. (lp#434657)
  * enhancement: better MACHINE-VERSION on Darwin x86 and x86-64. (lp#668332)
  * enhancement: (FORMAT "foo" ...) and similar signal a compile-time warning. (lp#327223)
  * enhancement: no more "in: LAMBDA NIL" messages from the compiler for forms
    processed using EVAL -- now the appropriate toplevel form is reported instead.
  * enhancement: more legible style-warnings for inappropriate IGNORE and IGNORABLE
    declarations. (lp#726331)
  * enhancement: :NOT-NULL option has been added to alien C-STRING type to indicate
    that NIL/NULL is excluded from the type.
  * enhancement: SB-INTROSPECT:MAP-ROOT allows mapping over pointers contained in
    arbitrary objects.
  * optimization: SLOT-VALUE &co are faster in the presence of SLOT-VALUE-USING-CLASS
    and its compatriots.

    stack-allocated values out of their dynamic-extent. (lp#310175)
  * bug fix: attempts to use SB-SPROF for wallclock profiling on threaded
    x86-64 builds caused a type-error.
  * bug fix: calling COMPILE with something else than a lambda-expression as the
    second argument reports a more sensible error. (lp#718905)
  * bug fix: invalid combinations of :PREDICATE and :TYPE options in DEFSTRUCT

    CALL-NEXT-METHOD work correctly. (regression from 1.0.45.19)
  * bug fix: several foreign functions accepting string also accepted NIL and
    consequently caused a memory fault at 0 now signal a type-error instead.
    (lp#721087)
  * bug fix: under rare circumstances, constraint propagation could rewrite a
    variable reference to refer to a variable not in scope, causing an error
    during physical environment analysis when attempting to close over the
    variable. (lp#551227)

debian/1.0.46.0-1

sbcl.1.0.46

sbcl_1_0_46

changes in sbcl-1.0.46 relative to sbcl-1.0.45:
  * enhancement: largefile support on Solaris.
  * enhancement: SB-PROFILE:REPORT now supports :LIMIT and :PRINT-NO-CALL-LIST
    arguments (lp#710017)
  * enhancement: SB-PCL:+SLOT-UNBOUND+ is exported, making it possible to
    distinguish unbound instance slots when using STANDARD-INSTANCE-ACCESS
    &co. (lp#718039)
  * optimization: ERROR and CERROR are approximately 5 times faster.
  * optimization: optimized constructors are used for MAKE-INSTANCE of classes
    with applicable non-standard (SETF SLOT-VALUE-USING-CLASS),
    SLOT-BOUNDP-USING-CLASS, and INITIALIZE-INSTANCE :AROUND methods, speeding
    up instance creation in those cases.
  * optimization: arithmetic operations with multiple constant arguments in now
    have them reduced at compile-time. (lp#676414)
  * optimization: determining current character position on string-streams for
    pretty-printing was overly slow.
  * bug fix: local tail calls to DYNAMIC-EXTENT functions can no longer cause
    lifetime analysis to overwrite closed-over variables (lp#681092).

    safe (lp#673630).
  * bug fix: Solaris/x86-64 wasn't getting built with lutex support by
    mistake. (lp#667297).
  * bug fix: CONSTANTLY generated functions had bogus lambda-lists. (lp#713626)
  * bug fix: RUN-PROGRAM :PTY option was racy on OpenBSD. (lp#669485)
  * bug fix: UNINTERN takes a symbol, not a symbol designator -- could previously
    unintern the wrong symbol with the same name. (lp#693796)
  * bug fix: COPY-PPRINT-DISPATCH always has access to a pristine table,
    making it possible to restore the initial table if it has been messed up.
    (lp#678409)

debian/1.0.45.0-1

sbcl.1.0.45

sbcl_1_0_45

  * enhancement: ~/ and ~user/ are treated specially in pathnames.
    Refer to documentation for details.
  * enhancement: ASDF has been updated to version 2.010.
  * optimization: mutated closed-over variables that are only accessed by
    DYNAMIC-EXTENT closures (currently only FLET and LABELS functions
    declared to be DYNAMIC-EXTENT) are stored directly in their containing
    stack frame, rather than allocating a VALUE-CELL (lp#586103).
  * optimization: UNWIND-PROTECT cleanup functions are now declared
    DYNAMIC-EXTENT.
  * bug fix: backtracing function with &REST arguments now shows the full
    argument list. (lp#310173)
  * bug fix: return types for functions with complex lambda-lists are now
    derived properly (lp#384892)

    long string arguments slowed the compiler down to a crawl.
  * bug fix: closure VALUE-CELLs are no longer stack-allocated (lp#308934).
  * bug fix: non-standard MAKE-METHOD-LAMBDA methods could break RETURN-FROM
    in the DEFMETHOD body.
  * bug fix: #<SB-C::DEFINED-FUN ...> should no longer appear in compiler
    messages, being instead replaced with the corresponding function name.
  * bug fix: don't derive overly complex unions of numeric types for arithmetic
    operators. (lp#309448)

sbcl.1.0.44

sbcl_1_0_44

changes in sbcl-1.0.44 relative to sbcl-1.0.43:
  * enhancement: RUN-PROGRAM accepts :EXTERNAL-FORMAT argument to select the
    external-format for its :INPUT, :OUTPUT, AND :ERROR :STREAMs.
  * enhancement: ALLOCATION-INFORMATION also provides the page the object
    resides on.
  * enhancement: default dynamic-space size can be configured at build-time
    without touching source, using the --dynamic-space-size argument to make.sh.

    as a place.
  * enhancement: ASDF has been updated to 2.009.
  * enhancement: the system detects known type-erros in calls better,
    signalling a full warning about violated proclaimed FTYPEs and violations
    of derived FTYPEs within the same file, including self-calls.
  * enhancement: new function: SB-EXT:DELETE-DIRECTORY is now provided.
  * optimization: constant-folding exploits numeric and character types, in
    addition member types.
  * optimization: numeric, character and member types that are inhabited by
    exactly one value are tested with EQL.

    Branches are simplified before performing if/if-conversion, and simple
    equivalent branches (that only read the same constant or variable) are
    merged.
  * improvements to the Windows port:
    ** change: canonical unparsing form for pathname namestrings now uses / as
       directory separator. NATIVE-NAMESTRING still uses \ as the separator.
    ** bug fix: stackoverwriting due to incorrect usage of PeekConsoleInput
       on Windows. (thanks to Kalyanov Dmitry)
    ** bug fix: build now works on cygwin with GCC 4.x installed. (thanks to
       Kalyanov Dmitry)
    ** bug fix: run-sbcl.sh now works on Cygwin. (thanks to Kalyanov Dmitry)
  * bug fix: compiler failed to derive the result-type of MAKE-ARRAY as
    (AND VECTOR (NOT SIMPLE-ARRAY)) when appropriate. (lp#309130)
  * bug fix: (THE (VALUES ...)) in LOAD-TIME-VALUE caused a compiler-error.
    (lp#646796)

    where number of SIGALRMs per second is restricted. (lp#375515)
  * bug fix: non-unicode builds no longer fail (broken since 1.0.36.15).
  * bug fix: compile-times no longer scale linearly with the size of
    quoted lists in source-code. (lp#654289)
  * bug fix: better errors for unknown external-formats in OPEN. (lp#561974)
  * bug fix: DEBUG>SPEED no longer degrades ALIEN-FUNCALL performance quite
    so badly. (lp#654485)
  * bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCES-BY-NAME no longer signals
    an error for eg. STRUCTURE. (lp#458015)

    (lp#613871, thanks to Roman Marynchak)
  * bug fix: more reliable &REST list type derivation. (lp#655203)
  * bug fix: PPRINT-LOGICAL-BLOCK multiply-evaluated :PER-LINE-PREFIX,
    and issued pointles code-deletion notes for it, :PREFIX, and :SUFFIX.
  * bug fix: the compiler didn't utilize the proclaimed ftype for functions
    also declared NOTINLINE. (lp#655581)
  * bug fix: the compiler could attempt to emit constant left shifts of
    greater value than n-word-bits. (lp#309063)
  * bug fix: (SETF SYMBOL-FUNCTION) and (SETF FDEFINITION) clear derived
    type information for the function being set. (lp#659220)
  * bug fix: the system used to signal bogus STYLE-WARNINGs when functions
    containing self-calls were recompiled with a new signature, and failed
    to warn when a self-call using the old signature was left in. (lp#655126)
  * bug fix: incorrect FILE-POSITION on streams opened using :EXTERNAL-FORMAT
    :DEFAULT when the default external had character size other than 8 bits.
    (lp#657183)
  * bug fix: derived types of functions in the same file were implicitly
    trusted, leading to potential heap corruption when those function were
    defined incompatibly. (lp#657499)
  * bug fix: existing ASDF source registries are ignored when building
    contribs (lp#659105)
  * bug fix: short-form DEFSETF checks that the second argument is a symbol
    (lp#655824, thanks to Roman Marynchak)
  * bug fix: (SETF MACRO-FUNCTION) clobbered macro-definitions before
    package-lock violation was detected. (lp#660752)

    (lp#655872)
  * bug fix: SB-POSIX:FORK now signals an error if an attempt to
    fork with multiple Lisp threads running is made on every platform,
    not just Darwin. (lp#451111)
  * bug fix: SB-BSD-SOCKETS and SB-SIMPLE-STREAMS could leave stale finalizers
    around when core was saved, which could cause undefined behaviour when the
    core was reified.
  * bug fix: Allow UNTRACE of functions that are no longer defined
    (lp#667657, thanks to Attila Lendvai)
  * bug fix: MAKE-ARRAY calls with invalid keyword argument lists now signal a

    event-loop by default. (lp#316072)
    ** In addition to streams created by explicit calls to MAKE-FD-STREAM this
       affects streams from CL:OPEN.
    ** Streams from SOCKET-MAKE-STREAM still participate in serve-event by
       default, but this is liable to change: applications needing serve-event
       for socket streams should explicitly request it using :SERVE-EVENTS T
       in the call.
  * enhancement: SB-EXT:WORD type is provided for use with SB-EXT:ATOMIC-INCF
    &co.

    (not in launchpad, reported by sykopomp in #lispgames)
  * bug fix: package-locks failed to protect against compile-time effects of
    DEFUN when the symbol previously had a macro definition. (lp#576637)
  * bug fix: spurious ignore warnings even given (DECLARE IGNORE) in methods
    when parameter bindings mutated.  (reported by Faré Rideau; lp #611361)
  * bug fix: workaround for compiler hang in ORDER-UVL-SETS (lp#308914)
  * bug fix: evaluation in debugger REPL works using the global context when
    in frames that do not have sufficient debug information.
