Well, you will have to somehow narrow down the conditions to reproduce
the problem, but I recently wasted an entire day on a nasty bug. It
turns out, the shared library found first by the process wasn't
compiled with thread support. This doesn't cause an immediate crash,
but only under certain conditions. Anyway, when I hear threads I now
think: do everything from scratch in a private directory. Even if you
don't get a crash, you may end up with corruption of important data.

Anyway, once again: with threads, don't trust any existing build.

There was also a recent change in build flags, where --nostartfiles
gets left off, but this usually causes the build to fail (and maybe
only on x86_64.
