with gcc test.c -O2 it fails
with gcc test.c -O2 -mpclmul it succeeds.

No you're right.
I could add, though, that the compiler should have said something.
Also, why did it compile just fine with -O0?

The following trivial program:
#include wmmintrin.h
int main()
{
__m128i a, b;
_mm_clmulepi64_si128(a, b, 1);
}
Produces the following error at compile time:
In file included from test.c

It does compile with -march=westmere or later. I guess this is intended
behavior.

Oh, and to add, if you change the double to an int, it works.

I should point out that fixing the actual bug in question will fix the ICE
itself.
