--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Here is one which does not use pointers and inlining does not matter:
int ipos = 0;
int f (int world)
{
  int searchVolume = world;
  int currentVolume = 0;
  while (currentVolume != searchVolume && searchVolume) {
    currentVolume = searchVolume;
    if (ipos != 0)
      searchVolume = 0;
    else
      searchVolume = 1;
  }
  return (currentVolume);
}
int main()
{
  const int i = f (1111);
  __builtin_printf ("%d\n", (int)(i));
  if (i != 1)
   __builtin_abort ();
  return 0;
}
