[Boost-users] boost::regex_match throws exception

I build boost::regex 1.34 using Borland BDS 2006.
Simple regular expresions works fine, but I have problem with this regular expresion:
^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)+$
if a try to match it with any string longer then 22 bytes, regex throws exception.
After some investigations i simplified regular expresion to
^[10+]*@$
and it still throws exception

code I use:
        boost::regex e("^[10+]*@$");
        boost::match_results<std::string::const_iterator> what;
        if(0 == boost::regex_match(input, what, e, boost::match_default | boost::match_partial)) // here function throw exception
        {
                throw std::runtime_error("Invalid data entered - this could not possibly be a valid card number");
        }
        if(what[0].matched)
        {
                return true;
        }
        return false;
