That stack trace looks like the automatic clean up of the ObjectCache with the DefaultFont within it is related somehow to the crash. How the DefaultFont is managed has changed, to address bugs ironically, and in a general sense the clean up the stack trace looks just fine to me, it's roughly what I'd expect to happen. However, I don't have any clear idea why in this instance the crash has occurred. Given there isn't any obvious amiss we are unfortunately are left to widen out the search for what is amiss. Does running an OSG example like osgtext fail? Do others in the OpenMMW community seen this same crash? Is it possible to run OpenMMW single threaded to see if there might be some thread interaction? What OS/compile and OpenMMW version combination are you using? One possible cause of crash like this is memory corruption during the run of the application that is only revealed on clean up. Using a memory tools like valgrind might be spot this type of issue. Perhaps others might have seen something similar and can help shed some light on the nature of the crash. If it's possible to recreate the crash with an standard OSG example, or a small modification of one, then this would be really helpful for me to jump in a start investigating the issue. Cheers.
