--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
handle_vector_size_attribute does:

  /* Build back pointers if needed.  */
  tree new_type = build_vector_type (type, nunits);

  /* Build back pointers if needed.  */
  *node = lang_hooks.types.reconstruct_complex_type (*node, new_type);


But the default reconstruct_complex_type never reapplies the attributes back on
it. (I Have not looked into the c++ front-end's implementation to about the
same).
