I see, in this particular case it will work if dynamic stack 
allocation works and if you have guards on the stack size (page 
traps at the end of the stack).

The optimization is very limited, since it only works for 
returning one variable length structure under certain 
circumstances, but then again it is a common case for types where 
you want to do temporary allocation and prepending/appending 
something before making a system call or similar.
