Created attachment 94775 [details] gdb backtrace
Unfortunately, this backtrace is useless because it doesn't show any symbol names.
It might be easier to do this with glretrace than with Wine.

--with-optimize-option= --disable-optimized --enable-expensive-checks
Does building LLVM without these options help, or maybe with --enable-optimized instead of them?
