Ahh, if you're never actually seeing a SEGV in __lll_unlock_elision, this may indeed be something far more subtle than a double unlock and, in fact, I'd be even MORE interested in having you run the same batch of testing on an otherwise identical (ie: Ubuntu 16.04, blah blah blah) Skylake system.
It may well be a subtle glibc bug on powerpc, or a whackadoo silicon bug, or a more generic glibc bug or still a mongo bug, but the more data we can scrape up (I mean, unless you accidentally stumble on the bug in the process and fix it, then yay), the better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640518 Title: MongoDB Memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1640518/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
