Crash when comparing two .so files (Python 3.12)

I'm using diffoscope 252 on Fedora 39 (Python 3.12) and the tool crashes for me every time I try to compare to .so files.

Here I am using just two random libraries from my system:

$ diffoscope libixml.so.11.1.2 libjansson.so.4.13.0

During handling of the above exception, another exception occurred:

The fix for me is to add a b in the line:

line = ObjdumpDisassembleSection.RE_SYMBOL_COMMENT.sub(rb"\1", line)
