--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Valid C testcase that crashes the same way:

float f (__typeof (__builtin_pow) fn, float x)
{
  return fn (x, 2);
}

gimple_call_fnspec doesn't return anything for an indirect call to a
const function (where gimple_call_flags would say ECF_CONST).
