Milestone:  To Be Determined           |  Component:  xpressive
  Version:  Boost 1.67.0               |   Severity:  Problem

 example:

 {{{

 cmatch  match;

 cmatch  mat2;

 cregex rex = tcompile("(?P<ErrorCode>\\d{5})");

 if( regex_match("error10205",match,rex) )
 {

         mat2 = match;

         string strErr = mat["ErrorCode"];  //  Here will not get the match
 string

 }
 }}}

 It's cause by funciton:
 **void swap(match_results<BidiIter> &that)**

 in **match_results.hpp**  file.

 I had fix the bug, by adding

 == this->named_marks_.swap(that.named_marks_);

 after line 668.
