--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The logic is:
  if (warned || out_of_bound)
    {

      if ((out_of_bound && warn_strict_flex_arrays)
          && (((sam =3D=3D special_array_member::trail_0)
                || (sam =3D=3D special_array_member::trail_1)
                || (sam =3D=3D special_array_member::trail_n))
              && DECL_NOT_FLEXARRAY (afield_decl)))
              warned =3D warning_at (location,=20
...
      if (DECL_P (ref))
        inform (DECL_SOURCE_LOCATION (ref), "while referencing %qD", ref);
      if (rec && DECL_P (rec))
        inform (DECL_SOURCE_LOCATION (rec), "defined here %qD", rec);


The checks before calling inform should include a check for warned .
