Comment (by jakzale):

 Actually, it is seems to be the other way round.

 Apple's clang is based on LLVM 3.5, and it seems to have some difficulties
 with compiling the assembly code generated by LLVM used as backend (which
 is probably newer).

 Using the version of clang that comes with the LLVM used as a backend for
 GHC seems to sort out the problem for me.

 Try `PATH=/path/to/llvm ghc -fllvm File.hs` to ensure that GHC uses the
 correct version of clang.
