These are "my" animals (running at a local university). There's a couple
interesting details:
1) the animals run on the same machine (one with gcc, one with clang)
2) I did upgrade the OS and restarted the machine on 2024/02/26, i.e.
right before the failures started
These might be just coincidences, but maybe something got broken by the
upgrade ... OTOH it's weird it'd affect just HEAD and none of the other
branches, and on two difference compilers.
Just to be sure I removed the buildroot, in case there's something wrong
with ccache. It's a wild guess, but I don't have any other idea.
