I confirm that the demo program works.  However, in my use case, it doesn’t.  I have a function that is used to fill both a RMB Fl_Menu_Button and the Fl_Menu_Bar (in this case Fl_Sys_Menu_Bar).  I fill the menu using the base class Fl_Menu_, like:


 void ImageView::fill_menu( Fl_Menu_* menu )
 {
     menu->clear();

     int idx = 1;

     menu->add( _("File/Open/Movie or Sequence"),
                      kOpenImage.hotkey(),
                      (Fl_Callback*)open_cb, browser() );

     menu->add( _("File/Open/Single Image"), kOpenSingleImage.hotkey(),
                (Fl_Callback*)open_single_cb, browser() );

     mrv::media fg = foreground();
     if ( !fg )
     {
         menu->add( _("File/Open/Directory"), kOpenDirectory.hotkey(),
                          (Fl_Callback*)open_dir_cb, browser() );
         menu->add( _("File/Open/Session"),
                    kOpenSession.hotkey(),
                    (Fl_Callback*)open_session_cb, browser() );
     }

….etc….
}


What happens is that the Fl_Sys_Menu_Bar is filled once, but when the function is called again, it does not clear it.
