-----------------------------------------------+----------------------------
 Sending a std::map (or std::set) of size greater than 1 causes an
 MPI_ERR_TRUNCATE error. The following code reproduces this error:


 {{{
 #include <boost/mpi.hpp>
 #include <boost/serialization/map.hpp>

 int
 main( int argc, char * argv [] )
 {
   boost::mpi::environment env(argc, argv);
   boost::mpi::communicator world;

   if(world.rank()==0){
       std::map<int,int> test;
       test[1]=50;
       test[2]=100;
       world.send(1, 1, boost::mpi::skeleton(test));
       world.send(1, 1, boost::mpi::get_content(test));
       std::cout << "sent" << std::endl;
   }
   else{
       std::map<int,int> test;
       world.recv(0,1,boost::mpi::skeleton(test));
       world.recv(0,1,boost::mpi::get_content(test));
       std::cout << test.size() << std::endl;
   }
 }
 }}}
