The primary cause is that Premiere attempts to release a mutex that wasn't initialized or was previously deleted. That isn't clear because of a secondary bug in the error handling crashed after that, hiding the details of the original bug. All of this happend in a static destructor that really looks like it should not have happened at static destruction time. It looks suspiciously like the timeline GPU node somehow wasn't freed properly at exit, and waited until static destruction time where destruction order problems caused it to fail.
I'm not sure why this would crash repeatably on one system and not others - unless there was something different about the configuration, perhaps a GPU related plugin that changes the order of destruction of the application internal structures.
