Not only one software package is affected by this bug. "Most" software buil=
ds
are affected. As Andreas mentioned correctly, the fix is also beneficial for
other projects/target software.

There are so many packages with customized memory settings for s390x at
openSUSE, and the Maintainers can only shake their head about this behaviou=
r.
But let's progress step by step.

I have luck, that also IBM customers are raising questions regarding that n=
ow.=
