3428	Boost::regex brackets after  \\??	NLegende@…	John Maddock	"For example declare:
const boost::regex format(""match\\??(match)"");
and run program.

If I use brackets after \\?? I get error ""Microsoft C++ exception: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::regex_error> >""

If I use brackets after (\\?)? then it works.
