I have seen this error message within our build result of gcc13-testresults:

Can it be related to the patch fixing https://bugzilla.opensuse.org/show_bug.cgi?id=1188441 (what Segher meant upstream)?

I think this is related to the debugging effort for that z15 stability issue.

bsc#1214702 that is.

What is not public for the community...
I am looking, whether we can receive input during our openSUSE zSystems meeting  about it today in the evening.

I would rather wait before announcement, but because of the meeting... It seems we have a _workaround_ for bsc#1214702. It didn't fail for 20 hours, let's wait a little longer if it really helped.

Ihno has explained the background of the bugreport in our meeting now.
