--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Also:
  printf("\n  Finally: 0x%016lx, how silly can you get?\n",
    (unsigned long)((1 << 24) << 7));

This is undefined as shifting into the sign bit is undefined.
use instead:
  printf("\n  Finally: 0x%016lx, how silly can you get?\n",
    (unsigned long)((1ul << 24) << 7));
