The following should work without problem

class A {
public:
    int a;
    int *b;
    template<class Archive> void serialise(Archive & ar, const unsigned int 
version) {
        ar & a;
        ar & b;
    }
};

If you still have a problem you could save all the objects first

ar & my_obect;

You don't have to do anything else.  The serialization library includes
the tracking of repeated objects.
