Investigating this issue since autoremoval of pychopper from sid kicked in: when reading the source code of python-parasail, I've hit a comment in the decode implementation saying:
# The C interface allocates unaligned memory but does not provide a
# means of deallocating it. The parasail_free() is for aligned
# memory only. On Windows, this is an error. On OSX/Linux, free()
# is the same for aligned and unaligned.
Since memory alignment is also important on arm64 and a few
other architectures, my guess would be that something is going
wrong here and needs adjustment to handle more platforms like
the Windows one. Why did I look at decode? Because this is the
method invoked during the crash:
[…]
File
"/build/reproducible-path/pychopper-2.7.10/.pybuild/cpython3_3.13_pychopper/build/pychopper/parasail_backend.py",
line 30, in process_alignment
fo = first_cigar(aln.cigar.decode.decode())
^^^^^^^^^
File "/usr/lib/python3/dist-packages/parasail/bindings_v2.py", line
403, in cigar
return self.get_cigar()
~~~~~~~~~~~~~~^^
File "/usr/lib/python3/dist-packages/parasail/bindings_v2.py", line
390, in get_cigar
raise AttributeError("'Result' object has no traceback")
AttributeError: 'Result' object has no traceback. Did you mean:
'_cigar'?
I may continue tomorrow, in the context of the Advent calendar
bug squashing party. Hopefully this is really just a matter of
adjusting the decode implementation of python-parasail, but I'm
not sure of the status yet.
In hope this helps,
