--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> ---
I've posted a patch for this in July (but it had fallout, as expected...).  IL
after that fix:

test ()
{
  int i;

  <bb 2> [100.00%]:
  i_8 = num;
  MEM[(int *)&a] = 0;
  MEM[(int *)&a + 4B] = 0;
  MEM[(int *)&a + 8B] = 0;
  return;

}
