--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Slightly cleaned up:
int a = 3, c;
short b = 5, d, f;
volatile short e;

__attribute__((noipa)) void
foo (void)
{
}

int
main ()
{
  for (f = 29; f != 33; f++)
    {
      int g = a;
      if (b)
        if (a)
          for (a = b = 0; b <= 8; b++)
            ;
      e;
      e;
      for (c = 0; c != 14; ++c)
        e;
    }
  b = d;
  foo ();
  if (a != 0)
    __builtin_abort ();
  return 0;
}
