I've seen some of these memory leaks and crashes in GtkAda 2.4. I think 
GtkAda 2.4 shipped with a (even then) outdated version of GtkExtra and 
when using a newer GtkExtra at least the Plot Realtime worked. I'm not 
sure but I doubt GtkAda does much memory allocation itself, so I'd 
suspect memory leaks originate in Gtk and especially in GtkExtra.
