when this first came up, it thought that it would be possible to do this. Now that I think about this, I don't see that its possible.
I think something to this effect can be implemented resorting to <drumroll>helper support</drumroll>. Non-tested pseudocode follows. The idea is not to supress tracking (which can't be done) but rather to move stack-based objects to a safe location so that Boost.Serialization does not get confused by objects with potentially the same stack address. template<typename T> struct non_tracking { non_tracking():p(0){} non_tracking(const T& t):p(&t){} const T& get()const{return *p;} const T* p; struct helper { typedef std::list<T> table_type; table_type table; }; template<class Archive> void save(Archive & ar,const unsigned int)const { helper::table_type& table=ar.get_helper<helper>().table; table.push_back(*p); ar<<table.back(); } template<class Archive> void load(Archive & ar,const unsigned int) { helper::table_type& table=ar.get_helper<helper>().table; T t; ar>>t; table.push_back(t); ar.reset_object_address(&table.back(),&t); p=&table.back() } }; Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
