The correct program should be:

   po::options_description desc("Allowed options");
   desc.add_options()
       ("help", "produce help message")
       ("arg1", po::value<string>()->implicit_value( string("") ), "optional arg1 description") ;
   {
      // ******* This test fails on boost 1.59, can't cope --arg1 10, only --arg1=10 *******
      char* argv[] = {
            const_cast<char*>("test_program_options_implicit_value"),
            const_cast<char*>("--arg1"),
            const_cast<char*>("10")
      };
      po::variables_map vm;
      po::store(po::parse_command_line(3, argv, desc), vm);  // populate variable map
      po::notify(vm);
      BOOST_CHECK_MESSAGE(vm.count("arg1"), "Expected arg1");
      BOOST_CHECK_MESSAGE(vm["arg1"].as<string>() == "10", "Expected arg1 with value of 10 but found '" << vm["arg1"].as<string>() << "'");
   }
