Description:
------------
The last of the example strings below should be
  "ababba"

The string "ababaa" does not match as the pattern for the previous (2nd) iteration is "ba", hence to match b\1 on the third iteration, the rest of the string needs to be "bba"

other matching strings

  "abaaba"

  "abaaababba"

  "ababbabbba"



Reproduce code:
---------------
---
From manual page: regexp.reference.back-references
---

For example, the pattern (a|b\1)+  matches any number of "a"s and also "aba", "ababaa" etc.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
