--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
      if (TREE_CODE (field) =3D=3D FIELD_DECL
          && DECL_INITIAL (field)
          && TREE_TYPE (field) !=3D error_mark_node)
        {
          unsigned HOST_WIDE_INT width
            =3D tree_to_uhwi (DECL_INITIAL (field));
          tree type =3D TREE_TYPE (field);
          if (width !=3D TYPE_PRECISION (type)) <--- Crash
            {

Obvious introduced by the TYPE_PRECISION change to ICE on vector types:
