     Type:  Bugs                    |      Status:  new        
Milestone:  To Be Determined        |   Component:  regex      
  Version:  Boost 1.44.0            |    Severity:  Problem    
 Keywords:                          |  
------------------------------------+---------------------------------------
 code does not match documentation. if matched==false length() does not
 return 0, instead it results in an assertion of "string iterators
 incompatible"
 docs state:
 {{{
 static difference_type length();

 Effects: returns the length of this matched sub-expression, or 0 if this
 sub-expression was not matched: matched ? distance(first, second) : 0).
 }}}

 Checked the source, code is broke.
