The code does not do what you want it to do:
You want:
#include <xmmintrin.h>

extern "C" double
fadd(double a, double b)
{
        __m128d a1;
        __m128d b1;
        __m128d c;
        double res;

        a1 = _mm_loadl_pd(a1, &a);
        b1 =_mm_loadl_pd(b1, &b);
        c = _mm_add_sd(a1, b1);
        _mm_storel_pd(&res, c);
        return res;
}


But the ICE is a regression from 3.3 so confirming on that
