--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
As you can see by the gimplification:
  _1 = std::_V2::system_category ();
  _2 = std::_V2::system_category ();
  _3 = _2->_vptr.error_category;
  _4 = _3 + 16;
  _5 = *_4;
  _6 = std::_V2::system_category ();
  _7 = OBJ_TYPE_REF(_5;(const struct error_category)_1->2B) (_6);
