What ICE? With what options? The testcase doesn't compile for me at -O0:
/tmp/t.ii:586:36: required from here
/tmp/t.ii:378:24: error: 'typeof' was not declared in this scope
__v *= (typeof(__v)) { __mult * __param.stddev(),
^
/tmp/t.ii:397:24: error: 'typeof' was not declared in this scope
__v *= (typeof(__v)) { __mult, __mult };
ah, -std=gnu++0x required ...
> ./cc1plus -quiet /tmp/t.ii -msse4 -std=gnu++0x
/tmp/t.ii: In function '__m128i

still not an ICE. It's an error. Compiles ok with optimization.
So - can you be a little more verbose?
