[Bug c++/36960] Reference variable in virtually inherited base corrupted under optimization

[pinskia at gcc dot gnu dot org]

  i = 0;
  upper.D.2127.ref = &i;
  upper.D.2125._vptr$Middle = &_ZTV5Upper + 12;
  return *((struct Lower *) &upper + (long unsigned int) *(int *)
&_ZTV5Upper)->ref;

This works on the trunk correctly.
