This is familiar but I cannot remember whether it got fixed or not now. I
thought llvm-gcc worked with llvm some months ago.

Sorry to be so lame,

This is usual indication that LLVM is miscompiled. I was hurt by the
same hting preparing the prerelease binaries for mingw32 as well. The
solutions were:
- Switch to never gcc
- Compile stuff in debug mode :(
