It's hard to know what could be causing this without at least knowing
where the exception is thrown. I looked at all the throw sites and all
of them related to the Win32 thread synchronization primitives so it
is very strange.

One thing you can try is to update to the latest 2.5.0 pre-release
(which is currently at the release candidate stage). In 2.5.0 we have
switched to C++11 threading API so maybe that will help. For
instructions on how to build ODB 2.5.0, see:
