There seems to be a part of the log missing here, if it's segfaulting in
the libc semctl() there used to be glibc bug for SEM_STAT_ANY which may
cause SIGSEGV:

This just says that the glibc bug is present so it's likely that the
same bug is causing segfaults on the rest of the architectures.

Looks like muticast groups is not compiled in kernel here.

We should handle this and report TCONF instead, however this is not a
regression, the test has been like this for three years.

This shouldn't really happen, what this says is that time jumped 51
years back. That is really absurd.

Can we have a backtrace here? It's impossible to say what happened here
without further debugging.

That's likely due to tst_pollutte_memory().

What are the overcommit settings on that machine?

This is probably worth fixing before the release if we manage to figure
out the cause.

That is known and reported:

Ritchard is trying to rewrite LTP cgroup library to solved this, it
should land in git repository in a month or two.
