Comment(by ufwt@…):

 crash example:
     boost::regex
 re("[a-z].*(d_notexiststring)",boost::regex::perl|boost::regex::no_except);

     std::string s="f";
     s.append(1024*100,'a');
     s.append("dd");
     boost::match_results<std::string::const_iterator> what;
     boost::match_flag_type flags = boost::match_default;

     std::string::const_iterator start, end;
     start = s.begin();
     end = s.end();
     boost::regex_search(start,end,what,re,flags);
