I said previously I'd apply the patch, but I wanted to check the
problem first.  No problem is showing at
https://tests.reproducible-builds.org/debian/rb-pkg/petsc.html
even in the experimental rebuilds.

I tried rebuilding in an experimental chroot on barriere.debian.org
porterbox (amd64), using libc6-dev 2.38-3 with 13.2.0-4.
No problem there either, even with libc6 version 28.

It sounds like some problem might have entered into ubuntu mantic.
I think it would be better to track down that problem rather than
papering over it and ignoring it.

Downgrading severity since the error is not reliably reproducible.

Is Ubuntu still affected by the problem?
