I just want to say that I managed to solve this problem without creating a temporary , thanks to this thread : http://old.nabble.com/(de)serializing-map%3Cconst-A*%3E-to5538474.html#a5596...http://old.nabble.com/%28de%29serializing-map%3Cconst-A*%3E-to5538474.html#a...
And here it is what I have got in my problem :
boost::shared_ptr<const TT> jj(new TT(5));
{ boost::archive::xml_oarchive oa(ofs); oa & BOOST_SERIALIZATION_NVP(jj); }
boost::shared_ptr<const TT> rjj;
{ void* xptr=&rjj; boost::shared_ptr<TT> *xxptr; xxptr=static_cast< boost::shared_ptr<TT> * > (xptr); boost::archive::xml_iarchive ia(ifs); ia & BOOST_SERIALIZATION_NVP(*xxptr); }
This is undefined behavior. I would strongly advise against it if there is a reasonable alternative.

Note that for better or worse, the serialization library does a lot of this kind of thing internally. If fact, a number of key facilities (e.g. export, usage of DLLS, etc depend on behavior which is technically undefined, but necessary to implement them. Just getting them to work at all was a huge challenge. I doubt that the above is any more risky than many usages of the library itself. Robert Ramey
