Milestone:  To Be Determined  |   Component:  None         
  Version:  Boost 1.36.0      |    Severity:  Problem      
 Keywords:                    |  
------------------------------+---------------------------------------------
 The perl expression (?<=.{3,3}).{6,6} passed in to boost regex results in
 Unmatched [ or [^

 ?<= signifies a backward looking positive assertion so a pattern match
 should be returning 6 characters starting at offset 4

 This works fine in perl. Any idea what part of the pattern is causing the
 issue?

 thanks

 Mark
