Ups, I have not click on "reply to all". Sorry.
Here a short test programm I used to test if there is a memory leak in
gdk_draw_pixmap

This program has no memory leak (at least on win95). Does it mean that
gdk_draw_pixmap is correct? Perhaps the memory leak is in
gdk_gc_set_clip_mask?

#include <gtk/gtk.h>
int main(int argc, char *argv[])
{
  int i;
  GdkGC *mygc;
  GtkWidget *window;
  GtkWidget *drawing_area;
  GdkPixmap *pixmap;
  gtk_init(&argc,&argv);
  window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
  drawing_area=gtk_drawing_area_new();
  gtk_widget_set_usize(drawing_area,300,300);
  gtk_container_add(GTK_CONTAINER(window),drawing_area);
  gtk_widget_show(drawing_area);
  gtk_widget_show(window);
  pixmap=gdk_pixmap_new(drawing_area->window,100,100,-1);
  mygc=gdk_gc_new(drawing_area->window);
  while (1)
    {
      for (i=0;i<2000;i++)
        {
          gdk_draw_pixmap(drawing_area->window,mygc,pixmap,
                          0,0,0,0,100,100);
        }
      sleep(2000); /* Windows uses msecs */
 
    }
}
