I've used Gtkmm2.8.3 version. The following code segment cause a huge memory leak. Can anyone please take a look and advice me what was wrong with it. My application is not a gtk window application but it just need to use the GDK level api to manipulate bitmap and save it out to disk. I turned on mtrace and it showed the leak is in X11.so.
