libvorbis does not like being compiled by a llvm backend.
I am the mac builder for Warzone 2100; recently I switched everything over to compile with clang but I found that warzone would crash on start up.
I determined that this only happens when libvorbis has been compiled with a LLVM backend (switching it to use gcc4.2 makes it work again).
I would really like to be able to use clang to compile libvorbis, so any ideas would be useful.
