[Beowulf] glibc in RHEL 7.3 causing problems?

Hi folks,

I'm helping some folks out with a cluster running RHEL7 and some new
RHEL 7.3 nodes they were bringing up were seeing segfaults in some
sysadmin compiled binaries, errors like:

[515255.354827] not_ok[19439]: segfault at b0 ip 00002ac97c7da65e sp 00007ffe91a8b1b8 error 4 in libc-2.17.so[2ac97c751000+1b6000]

Reverting those nodes to RHEL 7.2 solved the problem immediately.

Anyone else seen this?

I'll suggest they file a bug with Red Hat if they can track it down.

Hope this helps others!

All the best,
