The memory for compiling and the code size you obtain are pretty big and 
are not what I would expect for the small code you posted. We had this 
kind of problem before ... this kind of has a bad smell. There is 
probably a design issue hiding somewhere. I'll try to find some time to 
investigate a bit.
