CI failure

[frenzymadness]

I've spent some time figuring out what is happening with the last build in the CI.

Sometimes it fails on s390x with the following error:

But the build for Python 3.12 on amd64 is fine so it should not be a problem or a difference in Python/gcc settings coming from Fedora. Yes, the Py_FileSystemDefaultEncoding is deprecated in Python 3.12 but why doesn't it cause the same issue on amd64 or with the exact same Python version in the previous builds?

I've tried to compare the list of packages installed in the last two builds and there are only unrelated updates or the ones I don't expect to be troublemakers.

Another problem is that sometimes the job on ppc64le fails with a segfault during the compilation of pygit2 or cffi.

Hmm, the error code of gcc -11 might mean that there is a segfault so the deprecation error message mentioned above might not be the real cause of the issue and that would match with what happens sometime on ppc64le.

I'm not able to manually reproduce the problem. I've tried it on s390x bare metal and in the freshly built container on the same host and it works fine.

I'm going to disable the test and we can try to enable it back when we switch to newer Fedora release.
