> And here is a testcase that fails also for 4.0.0 and self contained also:
replace main with:
int main(void)
{
  if (sizeof(int) != sizeof(long))
    return 0;
  int *a = new int;
  long *b = new long;
  *a = 0;
  *b = 0;
  if (foo(2, a, b) != 6)
    abort ();
  return 0;
}

This is what you get when thinking about 2 steps ahead of yourself.
