Something similar may have happened to centos in the past: https://bugs.centos.org/view.php?id=11074

Bob/Daiki, is this a duplicate of other similar bugs you've seen recently?
Comment 3 Daiki Ueno 2017-08-30 08:03:52 UTC 
It's likely, but I can't say anything without examining the backtrace and the failing instruction.  Davide, could you try to collect more information as in the other bug 1482798?
