Description Miro Hrončok 2024-12-11 10:39:48 UTC 
This is pretty much the same thing as bz2330562 but for libcomps.

In Python 3.13.0:

>>> import libcomps
>>> i = libcomps.Comps()
>>> next(iter(iter(i.environments)))
Segmentation fault (core dumped)

This is with python3-libcomps-0.1.21-3.fc41.x86_64.


With Python 3.13.1 this code is called via dnf in https://github.com/rpm-software-management/dnf/blob/4.22.0/dnf/comps.py#L420

This causes anaconda to segfault and blocks update to Python 3.13.1.

Reproducible: Always

Or even:

>>> import libcomps
>>> i = libcomps.Comps()
>>> it = iter(i.environments)
>>> it2 = iter(it)
Segmentation fault (core dumped)
