Andrew, according to the valgrind community, the error Memcheck: mc_machine.c:329 (get_otrack_shadow_offset_wrk): the 'impossible' happened.
is probably due to the lock elision code accessing a hardware register that valgrind doesn't know about, so there isn't a shadow register to consult. Our valgrind guys will look into that aspect of things. In the meantime, they tell us that you can circumvent this problem by not using --track-origins. Could you please give this a try? -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
