Reduced testcase:
typedef float __v4sf __attribute__ ((vector_size (16)));
int ffg (__v4sf __A);
int main()
{
  float f = 1.f/0.f;
  __v4sf __tmp = __builtin_ia32_loadss (&f);
  __v4sf  a = __builtin_ia32_shufps(__tmp, __tmp, 0),
          comp = (__v4sf)__builtin_ia32_cmpunordps(a,a);
  return ffg(comp);
}
