Windows takes care of this for normal string items, but not for owner-drawn items or additional item-info. */ If it is inaccurate, why is that? How is it that GC happens in between creation of the widget value and its use in add_menu_item? Note that GC ought to be inhibited within set_frame_menubar from this line inhibit_garbage_collection (); to this line unbind_to (specpdl_count, Qnil); Does the GC happen inside that range, or after? Either way, it's a bug; the question is what bug.
