Milestone:  To Be Determined           |  Component:  regex
  Version:  Boost 1.61.0               |   Severity:  Problem

 Expression

 .*\.(?i:(doc|docx))

 matching

 a.doc
 a.DOC
 a.docx
 a.DOCX

 doesn't match a.DOCX but matches all other strings.

 If I change the order to

 .*\.(?i:(docx|doc))

 all strings are matched.

 Tested with Visual Studio 2012 and gcc 5.3
