--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
To avoid the #include, I've used
int a, b, c, d, e, f, g, h;

int
main ()
{
  for (; a; a--)
    for (d = 1; d <= 0; d++)
      for (; d;)
    if (h)
      {
        if (!g) __builtin_abort ();
        if (!0) __builtin_abort ();
      }

  for (f = 4; f; f--)
    {
      for (b = 0; b < 2; b++)
    c |= 1;
      e |= c;
    }

  return 0;
}

and that started to ICE with r181990.
