Bug in PCRE

Reported by: jchd18 Owned by: Jon
Milestone: Component: AutoIt
Version: Severity: None
Keywords: Cc:


A bug in recent releases of the PCRE library has been reported which may affect users running the beta (the release is OK):

In caseless utf modes, it is possible for character classes to be missing the lowercase version of some ascii characters.

Example below shows that the beta gives a wrong result (the range a-j is missed), yet the release behaves correctly:

ConsoleWrite(StringRegExpReplace("ABCDEFGHIJKLmonpqrstuvwxyz[\]^_` 123456 abcdefgijklmnopqrstuvwxyz", "(?i)([A-`])", "*") & @LF)

Advice: if you need the beta, make character ranges in classes more explicit, until Dev team can link a fixed version of PCRE in a new AutoIt beta or release.

Remark: no change in PCRE can be found in the changelog between release and beta but the code sample above clearly demonstrate they don't use the same PCRE version.

It can be related I will check

After a test 8.35 induce the regression if it is really a regression

Yes it is. It also crept in PCRE2 (10.00 and 10.10RC2 exhibit the same bug). No doubt it will be fixed soon by Philip Hazel & co.

Is it reported to Phillip Hazel?
Any new if PCRE2 (10.20)?

comment:5 Changed 8 years ago by jchd18

The bug was reported to the dev list and quickly fixed some time ago.
PCRE2 is moving forward. There is a RC being tested but I expect some time before the dust settles.

I notice that the last release ( dated 2015-07-10 uses PCRE v8.35 (dated 2014-04-04) instead of the last available version, 8.37 dated 2015-04-28. This explains why the bug in this "ticket" (rather a notice) can still show.

I confirm 8.37 is solving the pb
