A error when using long option description, program_options library
This runtime error only occurs when debug version, the release version has no such problem. The long option description can not be printed. My platform is vc7.1+stlport 4.62+boost 1.33, I also define the macro _STLP_DEBUG and BOOST_LIB_DIAGNOSTIC. Some extraction of my code: operatoins.add_options() ("difference,d", "Get all the word of mine, origin file, my file, output file") ("replace,r", "Replace the wrong pinyin with the right(delete maybe wrong chongma)" ", right file, origin file, new file") ("remove", po::value<string>(), "delete the word specified by regex expression") ("merge,m", "merge the files specified") ("regex", "match regex") ("files,f", po::value< vector<string> >(), "input file"); when print "Get all the word of mine, origin file, my file, output ", a runtime error occurs, the program terminates. Although I can give the debug version a short description and the release version a long description, it is boring. The error occur in the code call format_one()/format_description/format_paragraph The error code is line 361, options_description.cpp: if (line_begin + (line_length - indent) > par_end) { line_end = par_end; } else { line_end = line_begin + (line_length - indent); }

Please provide the minimal complete program that reproduces this, and I'll try to debug this. - Volodya
I change the demo code of program_option first.cpp as below, when I compiled with cl /MDd /EHsc /D "BOOST_ANY_DYN_LINK" /D "_STLP_DEBUG" first.cpp when run "first --help", a runtime error will occur. when cl /MD /EHsc /D "BOOST_ANY_DYN_LINK" first.cpp, there is no runtime error running "first --help". ---------------------------------------------------------------------------- ------------------- #include <boost/program_options.hpp> namespace po = boost::program_options; #include <iostream> #include <iterator> using namespace std; int main(int ac, char* av[]) { try { po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message, a very very very very very long long long long long long information") // The reason of rumtime error ("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"; } } catch(exception& e) { cerr << "error: " << e.what() << "\n"; return 1; } catch(...) { cerr << "Exception of unknown type!\n"; } return 0; } ---------------------------------------------------------------------------- ------------------------ I also trace the error and find it occurs in the code call format_one()/format_description/format_paragraph The error code is line 361, options_description.cpp: if (line_begin + (line_length - indent) > par_end) { line_end = par_end; } else { line_end = line_begin + (line_length - indent); } ----- Original Message ----- From: "Vladimir Prus" <ghost@cs.msu.su> To: <boost-users@lists.boost.org> Sent: Tuesday, September 06, 2005 1:51 PM Subject: Re: [Boost-users] A error when using long option description,program_options library
