Rather improbable test case demonstrating problem (771 bytes, text/plain)

Description Owen Taylor 2002-03-14 22:06:33 UTC 
No reference is held to the windows on updates_window list
during gdk_window_process_updates() ... if one got freed
during expose event processing (takes a lot of work ... need to 
destroy it, then iterate the main loop to get the destroy notify 
that removes it from the XID table) then it would still
try to access the destroyed window. (See bug 74311)

        * gdk/gdkwindow.c (gdk_window_process_all_updates): Fix rather
        improbable reentrancy problem if a window is destroyed
        while updates are being processed on another window. (Noticed
