 the following simple program using boost.program_options crashes with
 the boost macports


 #include <iostream>

 #include <boost/program_options.hpp>
 namespace po = boost::program_options;
 int main(int ac, char** av)
 {
         using namespace std;
 //locale::global(locale(""));
 // Declare the supported options.
 po::options_description desc("Allowed options");
 desc.add_options()
     ("help", "produce help message")
     ("compression", po::value<int>(), "set compression level")
 ;

 po::variables_map vm;
 po::store(po::parse_command_line(ac, av, desc), vm);
 po::notify(vm);

 if (vm.count("help")) {
         cout << desc << "\n";
     return 1;
 }

 if (vm.count("compression")) {
     cout << "Compression level was set to "
  << vm["compression"].as<int>() << ".\n";
 } else {
     cout << "Compression level was not set.\n";
 }
 }


 the problem lies in printing the options_description structure


 (gdb) r --help
