[cfe-dev] Clang crash using SSE intrinsics

Hi,

I'm seeing the following crash when attempting the compile the attached c file. I've reduced the original case as much as I could and still keep the failing behaviour. Changing the 'buffer' interactions (load or pointer increment), or removing the 'printv' seem to make it go away, as does compiling with anything other that -O0.

Code is fairly recent SVN: 
	llvm/trunk: 94955
	cfe/trunk: 94968
  ( I think they're sensible revision IDs?)

Please let me know if there's anything further I can do.

Thanks,
  David M
