There appears to be something still broken in the AIManager::update(). I'm rebuilding without threads to see if I can get a better backtrace. The crash is moderately intermittent and somewhat random except that it always occurs early on, just a few frames after system initialization (but before scenery loading is complete).
I have not been able to reproduce with --disable_ai_models on command line.
