Crashes just after an intro movie, 100% reproducable.

 Yes i tried that game few days ago and can reproduce that with llvm 3.5, but it works if mesa use (is compiled against) llvm 3.6 or llvm 3.7svn

Comment 2 Daniel Scharrer 2015-03-01 17:49:42 UTC

No crash here either with Mesa f8f3aa7 and LLVM r230332 (TAHITI, Radeon HD 7950).

Comment 3 smoki 2015-08-02 22:53:27 UTC

 I will close this as i have a game and it was working on day one with llvm 3.6+ and it works now with llvm 3.8.

 Please reopen if this is still an issue for you with llvm 3.6 or later.
