Extended Description
While compiling/"hacking on"/porting libc++ for Windows (!), I ran into a Clang assembler error:

clang++: error: assembler (via gcc) command failed with exit code 1 (use -v to see invocation)
Attached is -E and -S output. I'd really like to use Clang to hack on libc++, it's just so much... easier than with GCC.
