Hi Abe, 've added a Thread::Init() call into OpenThreads::SetProcessorAffinityOfCurrentThread(). This should hopefully solve the crash without you need to resort to adding a OpenThreads::Thread::Init() to your own application.
Could you do check out the svn version of the OSG, and revert your own adding of Init() and let me know how you get on. Robert.
