Yeah, that's what I've been seeing all weekend as well trying to build
the new upstream releases 2026.1 and 2026.2 in experimental.

I now tried with the old unstable version and hit it there as well
(after it went through the configure stage fine).

Interesting that it only started to fail yesterday, I'll try with an
earlier openmpi version then.
