If you statically link to boost.thread from a DLL, it uses the
_pRawDllMain hook to ensure that thread-local storage is correctly
cleaned up when a thread exits. Unfortunately, MFC also tries to use the
same hook, so the two are not directly compatible. I recommend you use
the DLL version of Boost.thread
