[boost] [serialization] "stream error" when port from boost_1.33 to boost_1.36

I just port a project using boost_1.33_1 to use boost_1.36.
The project has a Server class using a std::set<Server> serialization,
the serialization save and load functions code see behind.

I use gcc 4.1 and run on FC6.
The porting problem is, when the old boost_1.33 generates(save) a xml file,
then use  boost_1.36 load the xml throws an exception "stream error"!

the exception error code line : boost::archive::xml_iarchive ia(ifs);

How can i sovle it?

class Server
{
public:
   int id;
   std::string ip;
   int port;

private:
   static std::set<Server> lst_;

   static int dirty_;
};

#endif

#ifdef USE_SERVER_SERIALIZATION

#ifndef _SERVER_SERIALIZATION_
#define _SERVER_SERIALIZATION_

BOOST_CLASS_VERSION(Server, 1)
namespace boost {
   namespace serialization {

       template <class archive>
       void serialize(archive & ar, Server & t, const unsigned int ver)
       {
           ar & BOOST_SERIALIZATION_NVP(t.id);
           ar & BOOST_SERIALIZATION_NVP(t.ip);
           ar & BOOST_SERIALIZATION_NVP(t.port);
       }

   }
}

#endif

#endif

int Server::save(    const std::string & file)
{
   try {
       std::ofstream ofs(file.c_str(), std::ios::binary);
       {
       boost::archive::xml_oarchive oa(ofs);
       oa << BOOST_SERIALIZATION_NVP(lst_);
       }
   } catch(...) {
       return ERROR_ERROR;
   }

   return ERROR_SUCCEED;
}

int  Server::load(const std::string & file)
{
       std::set<Server> Server::lst_;
       try
       {
         std::ifstream ifs(file.c_str(), std::ios::binary);

         {
           boost::archive::xml_iarchive ia(ifs);
           ia >> BOOST_SERIALIZATION_NVP(lst_);
         }
       }
       catch(std::exception & e)
       {
                       std::cout  << e.what() << std::endl;
       }

       return 0;
}
