test case

I've tried to compile the file eigen/test/geometry.cpp from eigen[1] 2.0.15

It fails in the following way (with -O0 -emit-llvm):

<<<FAIL

clang: error: clang frontend command failed due to signal 2 (use -v to see
invocation)
<<<FAIL

I'm attaching the output of -save-temps. Since it is 1.3M in size every
invocation of clang takes very long and I've not yet delta-reduced it. I've
also only attached an xz-compressed version.

I'm on clang 3.0 git-6594942e98e25640f226aba622eb76bcaf0a521c
