I had problems yesterday with uploading the dump.
(In reply to Andreas Krebbel from comment #22)

Thank you for this hint!

One question to you as a compiler Expert:
Do you know any dependencies between gcc or other compilers and dependencies to
sub operating systems in virtualization?

SUSE people tried today the same with SLES 15 SP3 and it is not reproducible.
You tried it both with containerization and qemu (therefore, that can not be a
qemu issue, if both has been on s390x together with Fedora).
Additionally, you have been needing 12GB of memory for virtualization in
comparison to 4GB on openSUSE Tumbleweed. Anything is going wrong here with GCC
together with the sub operating system.

I have started a discussion about that (together with Fedora and Debian people)
on our factory mailing list:

If you are open to additional experiments in this direction for reproducing
based on Fedora (I can not run Fedora in the LinuxONE Community Cloud). Fedora
has released Fedora 35 in the last weeks. Have you got any possibilities to
upgrade and run these commands based on that?
