I've been seeing a few strange crashes in the LLVM backend when using wine. 
What version of wine are you using?  Does it work with an older version of
wine?

This isn't just another instance of "Clang is broken" / bug 44466, right?

llvm and mesa are all built with a multilib gcc, perhaps it's the culprit ?
Another bug similer to https://bugs.freedesktop.org/show_bug.cgi?id=44466 ?

I've had to force host and target to i386-pc-linux-gnu to get a proper lib32
llvm.....

Does it crash with DRAW_USE_LLVM=0?

If not, please try whether this patch can provide more information:

furmark output with llvm-3.1 and r600-llvm-compiler enabled

Wine doesn't fail anymore, now rendering only garbage, so there is progress!

No more crash, so closing, a new bug is opened for broken output.
