--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Mine then.  SSA form is corrupt:

  <bb 12> [local count: 858993466]:
  vect_cst__66 = { 1.0e+0, 1.0e+0, 1.0e+0, 1.0e+0 };
  _67 = {_6, _10, _13, _16};
  vect_cst__68 = _67;

  <bb 3> [local count: 6950038024]:
...
  # ivtmp_73 = PHI <ivtmp_74(5), 0(12)>
  _6 = *S_32;
