Comment(by ufwt@…):

 i chanage re_repeat'max , code:

 void changeRegexRepeatNum(boost::regex &regex,size_t max)
 {
     boost::re_detail::re_syntax_base*
 state=regex.get_data().m_first_state;
     while(state){
         switch(state->type){
             case boost::re_detail::syntax_element_rep:
             case boost::re_detail::syntax_element_dot_rep:
             case boost::re_detail::syntax_element_char_rep:
             case boost::re_detail::syntax_element_short_set_rep:
             case boost::re_detail::syntax_element_long_set_rep:
             {
                 boost::re_detail::re_repeat
 *repeat=static_cast<boost::re_detail::re_repeat*>(state);
                 if(repeat->max - repeat->min >max){
                     repeat->max = repeat->min + max;
                 }
             }
             break;
             default:
                 break;
         }
         state = state->next.p;
     }
