I have following class with stl container:

class storage : {
private:
   map<const char*, int, cmp> data_;

   friend class boost::serialization::access;

    template<class Archive>
    void save(Archive & ar, const unsigned int version) const
    {
        map<string, int> local;
        constDataIter iter;

        for (iter = data_.begin(); iter != data_.end(); iter++) {
           local[iter->first] = iter->second;
        }

        ar & local;
    }
}

This code works, but it slowly(full copy) and consume too much memory (x2) :-(

What is the best serialization strategy with such stl containers or
pointer to pod type?

I cannot change const char* to string, dont ask me why :-))

Thanks you for any advice.
