3941	match_results relies on string evaluated by regex_search()	David Klamet <davek@…>	John Maddock	"See example:
If ""text"" is altered or destroyed, ""matches"" becomes invalid.
Is this the desired behavior?
-----------------------


    string pattern=""^\\s*:(\\S+)\\s*"";
    string text=""    :command  "";

    boost::regex re(pattern);
    
    
    boost::match_results<string::const_iterator> matches;
    bool stat=boost::regex_search(text, matches, re);
    text="""";   //Truncate string
    cout<<matches[1].str()<<endl;  //<<Throws sting iterator not dereferencable exception
