 While using boost to serialize/deserialize, valgrind reports that there
 are memory leaks about it:

 And here is my code, very simple:
     template <class T>
     int deserialize(T& bidObj, const char *filename)
     {
         if (!filename) {
             std::cerr << "file name is empty"<<std::endl;
             return ERROR;
         }

         std::ifstream ifs(filename);
         assert(ifs.good());

         //boost::archive::text_iarchive iar(ifs);
         boost::archive::binary_iarchive iar(ifs);

         iar >> bidObj;  // object deserialized

         return ::OK;
     }
