--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This warning is from the front-end:
      else if (cp_tree_equal (TREE_OPERAND (init, 0), current_class_ref)
               && uninitialized->contains (field))
        {
          if (TYPE_REF_P (TREE_TYPE (field)))
            warning_at (EXPR_LOCATION (init), OPT_Wuninitialized,
                        "reference %qD is not yet bound to a value when used "
                        "here", field);
          else if (!INDIRECT_TYPE_P (type) || is_this_parameter (d->member))
            warning_at (EXPR_LOCATION (init), OPT_Wuninitialized,
                        "member %qD is used uninitialized", field);
          *walk_subtrees = false;
        }
