gtk_widget_destroy memory leak

["Guoling Gao" <gguoling gmail com>]

Hi,
I see memory usage is biger and biger during the same code running:
int main(int argc, char* argv[])
{
    gtk_init(&argc, &argv);
   
    GtkWidget* window;
   
    while (TRUE)
    {
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);   
        gtk_widget_set_app_paintable(window, TRUE);
        gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
        gtk_window_set_keep_above(GTK_WINDOW(window), TRUE);
        gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
        gtk_widget_set_size_request(window, 200, 200);
        gtk_widget_realize(window);
       
        gtk_widget_destroy(window);
    }
   
    gtk_main();
    return 0;
}
 
If there are bugs in gtk_widget_destroy? It sames that the memory is not freed.
Wants help.
