Yes, that's exactly what's happening. One thread call exit() while
another one is working, and it looks the one still working is trying to
access something that has already been destroyed by the exiting one,
causing a memory violation. The resulting signal 11 is caught and we get
the related trace, but unfortunately that doesn't tell us anything about
the first exception.
