Well, look at the memory usage. If the leak is in a specific function
calling it 10000 times will use all your memory. You should of course use

Well, obviously (?) the memory leak bug was introduced when porting the gdk
lib from linux to windows. And I guess it is a windows lib now that it is
ported.
