     Type:  Bugs                       |      Status:  new        
Milestone:  To Be Determined           |   Component:  regex      
  Version:  Boost 1.44.0               |    Severity:  Problem    
 Keywords:  regex named capture group  |  
---------------------------------------+------------------------------------
 If I have a named capture group that has the possibility of matching
 multiple times, the named group is always an empty string.

 See attached file for full example of it working / breaking

 Notice that in the case where broke==true that the group names are not
 unique and when broke==false they are.

 This problem could be caused by the partial results overwriting the good
 match.

 The commented out string e is a regex that works in .net 2.0. I didn't
 like having my hands tied to a platform/runtime which is reason for
 rewriting in c/c++
