At this point I'm starting to suspect a compiler bug (or hardware fault?)
on your machine. I spent awhile last night trying to replicate your
previous report and failed, both on x86_64/RHEL8 and Apple M4/Sequoia.
Moreover, we're not seeing the sort of instability in the buildfarm
that would inevitably appear if AV were as broken as it seems to be
for you.
