[boost] regex lib: bug with sets and back ref

Hello,

The following behavior seems to be a bug:

   * regex '([a-c]+)\1' finds 'abcabc' at offset 0 in text 'abcabc'

   * regex '([abc]+)\1' finds 'bcbc'   at offset 1 in text 'abcbc'

   * regex '([a-c]+)\1' finds nothing              in text 'abcbc'   ???

Can anybody confirm this?  Tried both POSIX and Perl syntax/match mode.

Ralph
