Package: libglx-mesa0
Version: 24.3.0~rc1-1
Severity: serious
Justification: makes other packages FTBFS
Forwarded: https://gitlab.freedesktop.org/mesa/mesa/-/issues/12452
Dear Maintainer,
When mesa was updated to 24.3 branch a few days ago, some packages of our
Qt/KDE team started to FTBFS on ppc64el with segmentation fault in tests:
-
https://buildd.debian.org/status/fetch.php?pkg=qtlocation-opensource-src&arch=ppc64el&ver=5.15.15%2Bdfsg-3&stamp=1736409866&raw=0
-
https://buildd.debian.org/status/fetch.php?pkg=pyside2&arch=ppc64el&ver=5.15.16-2%2Bb1&stamp=1736410659&raw=0
-
https://buildd.debian.org/status/fetch.php?pkg=pyside6&arch=ppc64el&ver=6.7.3-1&stamp=1736463626&raw=0
It can also be seen that autopkgtests of some reverse dependencies of mesa
fail on ppc64el, e.g. clutter:
https://ci.debian.net/data/autopkgtest/testing/ppc64el/c/clutter-1.0/56277784/log.gz
I managed to obtain a stack trace of qtlocation test on a porterbox:

This issues is present in 24.3.0~rc1-1 and 24.3.3-1 uploads, but not present
in 24.2.8-1. I was not able to bisect it further yet, first because lack of
time and second because there are some packaging differences between 24.2 and
24.3 uploads.
