--- Comment #26 from Tom Stellard tstellar@gmail.com --- I've pushed a work-arond for the crash to LLVM trunk, so if you use the latest version of LLVM from svn/git these games should not crash, but there may be some mis-rendering.
When I come up with a proper fix, I will post it to this bug (this could be a while).
