--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Likely latent w/o this rev. since we optimize at GIMPLE level to

  <bb 2> [local count: 536870923]:
  g2__lsm.6_23 = MEM[(uint32_t *)&g2 + 264B];
  MEM[(uint32_t *)&g2 + 264B] = g2__lsm.6_23;
  MEM[(int32_t *)&g1] = 0;
  g3.b.a = 45;
  printf ("%d\n", 0);
  return 0;

I will eventually have a more closer look.
