1d01fc100bb5bef5f5eaf92520b2e52f64ee1d6e)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir:

clang-12: note: diagnostic msg:
Strangely the failure only happens on the buildbot; I've not yet succeeded to
reproduce it on other systems, and since it's a Release build, it's almost
impossible to do any useful debugging.
It doesn't seem to be a generic Solaris issue (the Solaris/amd64 bot isn't
affected).
Note that the sparcv9 bot is running with -DLLVM_TARGETS_TO_BUILD=Sparc, but
that doesn't seem to be the issue either since other bots are targetting
non-x86
cpus, too, and don't show that failure.
I'm attaching the reproducer.
I'm totally at a loss what may be going on here and how to proceed. Any
guidance is appreciated.</pre>
