Crash when diffoscoping two files
Hey it seems like diffoscope errors out when I compare these two files:
$ diffoscope /var/cache/pacman/pkg/ansible-9.4.0-2-any.pkg.tar.zst /var/cache/pacman/pkg/ansible-9.4.0-4-any.pkg.tar.zst
realloc(): invalid next size
[1] 24531 IOT instruction (core dumped) diffoscope /var/cache/pacman/pkg/ansible-9.4.0-2-any.pkg.tar.zst I can not really make sense of the backtrace (to me it almost reads like a python bug), so any input would be appreciated
- Version: diffoscope 265
- Python: Python 3.12.2
- OS: Arch Linux (rolling)
Let me know if I should provide any more information!
