Comment (by monika.cienkus@…):

 It's strange but dynamically created communicator work fine.


 {{{
 #include <vector>
 #include <boost/mpi.hpp>
 namespace mpi = boost::mpi;
 int main(int argc, char argv[])
 {
    mpi::environment env(argc, argv);
    mpi::communicator world, c;

    std::vector<int> v(1);
    mpi::group wg = world.group();
    mpi::group g = wg.include(v.begin(), v.end());
    c = new mpi::communicator(world, g);

    if (!world.rank()){
       std::cout << "v.size : " << v.size() << std::endl;
       std::cout << "wg.size : " << wg.size() << std::endl;
       std::cout << "g.size : " << g.size() << std::endl;
       std::cout << "c.size : " << c->size() << std::endl;
 }

 return 0;
 }

 }}}
