Bug#852013: (no subject)

[Brett Smith]

On my system at least, diffoscope is segfaulting:

% TMPDIR=/tmp/diffoscope2 diffoscope --debug /tmp/ink*.tar
...
2017-01-20 20:51:05 D: diffoscope.comparators.utils.compare: Comparing
files <<class 'diffoscope.comparators.elf.ElfCodeSection'> .text> and
<<class 'diffoscope.comparators.elf.ElfCodeSection'> .text>
2017-01-20 20:51:05 D: diffoscope.comparators.utils.command: Executing
objdump --line-numbers --disassemble --demangle --section=.text
/tmp/diffoscope2/tmpjc5015ey_diffoscope/bin/inkscape
2017-01-20 20:51:05 D: diffoscope.comparators.utils.command: Executing
objdump --line-numbers --disassemble --demangle --section=.text
/tmp/diffoscope2/tmpctv5bsup_diffoscope/bin/inkscape
^Czsh: segmentation fault  TMPDIR=/tmp/diffoscope2 diffoscope --debug
/tmp/ink*.tar

I can reproduce this with timeout too.  If I run it with
`--preserve-status`, it exits 139, which means diffoscope got signal 11.

So to me it looks like the bug isn't that diffoscope is "forgetting" to
clean its tempfiles: it's not like the cleanup code is being routed
around or running with bad data.  Instead, a more critical bug causes
Python to abort abruptly before it gets to run the cleanup code.
