[llvm-dev] Buildbot failure in LLVM Buildbot on clang-ppc64be-linux-multistage

[Dmitry Vyukov via llvm-dev]

+llvm-dev to have at least 1 mailing list in CC

The failure is:

command timed out: 1200 seconds without output running [b'ninja',
b'check-all'], attempting to kill
process killed by signal 9
program finished with exit code -1
elapsedTime=2226.650064

I assume some tests hanged.
I see these passed:

PASS: ThreadSanitizer-powerpc64 :: pthread_atfork_deadlock3.c (76992 of 77005)
PASS: ThreadSanitizer-powerpc64 :: Linux/fork_syscall.cpp (76996 of 77005)

So presumably it's pthread_atfork_deadlock.c or pthread_atfork_deadlock2.c.
These tests reliably pass on my x86_64 machine... I am not sure how to
debug this. It would be useful to know what exactly test hanged and at
what stacks. Or can it be a flake timeout?
