4044,reset_object_address with library-created objects,Richard Hazlewood,Robert Ramey,"The archive reset_object_address method does not work for objects created by the serialization library.

This appears to be the issue as discussed here:
http://lists.boost.org/boost-users/2008/11/42417.php
It looks like the issue was never addressed.

The code below demonstrates.  Is this considered to be the desired behaviour?

I would've thought the object tracking should be applicable, regardless of how the object is constructed.

{{{
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/serialization.hpp>
#include <sstream>

struct Ob
{
    Ob() : m_(1) {}

    int m_;

    template <typename A>
    void serialize(A &a, const unsigned)
    {
        a & m_;
    }
};

int main(int, char *[])
{
    std::string serText;
    {
        std::ostringstream str;
        boost::archive::text_oarchive oa(str);
        Ob *p = new Ob;
        oa & p & p; // Serialize two instances; serialization lib will track second
        delete p;
        serText = str.str();
    }

    {
        std::istringstream str(serText);
        boost::archive::text_iarchive ia(str);
        Ob *p = 0;
        ia & p;
        Ob *newp = new Ob(*p);
        ia.reset_object_address(newp, p); // newp should now be used for future p uses
        delete p; p = 0; // Let's explicitly get shot of this
        ia & p;
        assert(p == newp); // Traps
        delete newp;
    }

    return 0;
}
