Why doesn't allow_unregistered work for me?

[KOLANICH]

I still get too many positional options have been specified on the command line on run()

The excerpt

boost::program_options::variables_map vm;
try{
	auto parsed = boost::program_options::command_line_parser(rawArgs.argc, rawArgs.argv).options(oDesc).positional(pd).allow_unregistered().run();  //too many positional options have been specified on the command line
	boost::program_options::store(parsed, vm);
	boost::program_options::notify(vm);
	auto rest = boost::program_options::collect_unrecognized(parsed.options, boost::program_options::collect_unrecognized_mode::include_positional);
} catch(std::exception &ex) {
	PROCESS_CASE_OF_SYNTAX_ERROR_WHATABLE_EXCEPTION(ex);
}
