I found the problem in my code, the BOOST_SERIALIZATION_NVP macro doesnt
seems to support the derivated classes. so I used
boost::serialization::make_nvp(....) instead

it replaces 
ar << BOOST_SERIALIZATION_NVP(boost::serialization::base_object<Father>(g));
by
ar << boost::serialization::make_nvp("son",
boost::serialization::base_object<Father>(g));

Hope this is gonna help someone...
