HI,
I am using boost 1.33.0 with g++ 3.4.2 on Sun.
The error is:

terminate called after throwing an instance of
'boost::program_options::multiple_occurrences'
  what():  multiple_occurrences
Abort (core dumped)

For the following code:

namespace po = boost::program_options;
  namespace fs = boost::filesystem;
  po::options_description generic("Allowed options");
  generic.add_options()
    ("help", "produce help message")
  ;

  po::options_description hidden("Hidden options");
  hidden.add_options()
    ("input-file", po::value< std::vector<fs::path> >(), "input file")
  ;

  po::options_description cmdline_options;
  cmdline_options.add(generic).add(hidden);

  po::positional_options_description p;
  p.add("input-file", -1);

  po::variables_map vm;
  po::store(po::command_line_parser(argc, argv).
            options(cmdline_options).positional(p).run(), vm);
  po::notify(vm);

  if (vm.count("help"))
  {
    std::cout << generic << "  input1 [input2 ...]\n" << std::endl;
    return 1;
  }

  std::vector<fs::path> inputFilenames;
  if(vm.count("input-file"))
  {
    inputFilenames = vm["input-file"].as<std::vector<fs::path> >();
  }

Thanks,
Chris
