[Boost-users] [1.34][program_options] crash on release builds on windows using msvc-8.0

17 May 2007

      hi,
i compiled boost for windows using the msvc-8.0 and msvc-8.0_64 targets.
the following code works perfectly on debug builds but crashes on the
marked line in x64 mode and goes into an infinite loop in x86 mode.

i used visual studio 2005 with and without service pack 1 and even tried
the head version of boost. everytime the crash occurs.

int main(int argc, char **argv)
{
      int width;
      int height;

      try {
          boost::program_options::options_description  cmd_options("program options");

          cmd_options.add_options()
              ("help", "show this help message")
              ("width", boost::program_options::value<int>(&width)->default_value(1024), "output width")
              ("height", boost::program_options::value<int>(&height)->default_value(640), "output height");

          boost::program_options::variables_map       command_line;
***>     boost::program_options::store(boost::program_options::parse_command_line(argc, argv, cmd_options), command_line);
          boost::program_options::notify(command_line);

          if (command_line.count("help")) {
              std::cout << "usage: " << std::endl;
              std::cout << cmd_options;
              return (0);
          }
          winx = width;
          winy = height;
      }
      catch (std::exception& e) {
          std::cout << e.what() << std::endl;
          return (-1);
      }
}

thanks for your help
-chris
