=head1 DESCRIPTIONThis document describes various features of OpenBSD that will affect how Perlversion 5 (hereafter just Perl) is compiled and/or runs.=head2 OpenBSD core dumps from getprotobyname_r and getservbyname_r with ithreadsWhen Perl is configured to use ithreads, it will use re-entrant library calls
OpenBSD's C<getprotobyname_r> and C<getservbyname_r> function in versions 3.7and later that will cause a SEGV when called without doing a C<bzero> ontheir return structs prior to calling these functions. Current Perl'sshould handle this problem correctly. Older threaded Perls (5.8.6 or earlier)will run into this problem. If you want to run a threaded Perl on OpenBSD3.7 or higher, you will need to upgrade to at least Perl 5.8.7.=head1 AUTHORSteve Peters <email@example.com>Please report any errors, updates, or suggestions to F<firstname.lastname@example.org>.
