> Is this bug report reproducible with SLES?

I don't think I've seen it happen there so far, but AFAICS even the upcoming
SLE15-SP4 is still on llvm11, so the situation is not comparable. Maybe we
should check if it also happens with llvm11 on openSUSE, or only with llvm12.

One thing I noticed is that the VMs for s390x in OBS seem to be a lot slower
than the ones that build SLE, and maybe also compared to the ones that Michael
was using in his manual tests where he couldn't reproduce it. So, maybe the
race is more likely to get triggered on less powerful machines.
