Not in my experience!

When IDL destroys a my_obj instance it will erase an object reference stored
in the my_obj class structure. It will *not* destroy the heap variable that
this reference refers to. So to avoid a memory leak you need

pro my_obj::cleanup
obj_destroy, self.another_obj
; Other cleanup tasks
end
