Subject: [PATCH] Caseless matching of backreferences with fixed length
 repetitions was broken.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From development SVN tree:

r746 | ph10 | 2011-11-15 16:07:02 +0100 (Út, 15 lis 2011) | 2 lines

6.  Lookbehinds such as (?<=a{2}b) that contained a fixed repetition were
    erroneously being rejected as "not fixed length" if PCRE_CASELESS was set.
    This bug was probably introduced by change 9 of 8.13.

Petr Pisar: Changelog entry removed.
