full error message

When trying to cross-compile on a BlueGene/Q with clang (r190771), I get the
following error and clang crashes:

clang:
/gpfs/vesta-home/hfinkel/rpmbuild/BUILD/llvm/include/llvm/Support/Casting.h:239:
typename llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X =
llvm::VectorType, Y = llvm::Type]: Assertion `isa<X>(Val) && "cast<Ty>()
argument of incompatible type!"' failed.
