This was while building current trunk of LLVM/Clang on OS X 10.9.5 with the latest XCode available for that platform.

[Quuxplusone]

Have you reported the problem to Apple bugtracker as you were instructed?

[Quuxplusone]

Attaching the files to reproduce would help as well!

Tried building LLVM/Clang trunk with latest binary Clang release from llvm.org, i.e. clang version 3.6.2 (tags/RELEASE_362/final), which worked for me. So consider this report invalid. Thanks.
