--- Comment #8 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
The patch totally overlooks that the index can wrap around during the traversal
of the CONSTRUCTOR:

          if (index_type)
            index = wi::ext (index, TYPE_PRECISION (index_type),
                             TYPE_SIGN (index_type));

so the new comparison code cannot reasonably work...
