--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
printf isn't needed, -O2:
int a, b[1] = { 0 }, c, *d = b, e, *f, g;

__attribute__((noipa)) int
foo (const char *x)
{
  (void) x;
  return 0;
}

int
main ()
{
  for (int h = 0; a < 2; a++)
    {
      int i;
      for (g = 0; g < 2; g++)
        if (a < h)
          {
            e = i % 2;
            c = *f;
          }
      for (h = 0; h < 3; h++)
        {
          if (d)
            break;
          i--;
          foo ("0");
        }
    }
  return 0;
}

is miscompiled as well.
