Hi Marco - Can you be more specific? Where does the memory fault happen?

The size depends on the scene you're rendering. Since the OpenGL 
feedback buffer is not dynamically resizable, one easy solution is to 
call gl2ps with growing buffer sizes, until the buffer is large enough 
(this is what is done in the example codes).
