--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Looking at this, I see in PRE:
  REALPART_EXPR <D.72413[_8]._M_value> = _25;
  IMAGPART_EXPR <D.72413[_8]._M_value> = _26;
  _19 = REALPART_EXPR <MEM <struct complex[16]> [(const struct complex
&)&D.72413][_8]._M_value>;

Should _19 be the same as _25 ?

I suspect if this is done, then the vectorizer would kick in and do the right
thing.
