--- Comment #10 from Henri Verbeet hverbeet@gmail.com 2012-03-25 10:26:23 CDT --- I know there are some issues with LLVM compiled by Clang and Mesa. (See http://llvm.org/bugs/show_bug.cgi?id=12151 and related bugs.) I'm not sure if this is the same issue or not though. Setting the DRAW_USE_LLVM=0 environment variable may be a workaround.
