 New Comment:

Please read what I said: it's already fixed in PHP 5.2.0RC1.
We'll update PCRE as soon as the new version is out, but there is no
bug in PHP and this issue doesn't affect it either.

You're missing the point of this bug report.  I created it because in
Bug #27525, you clearly state that you would pull in the latest pcre
when the bug is fixed.  Well, it *will* be fixed, so you should keep an
eye out for it when it is (in fact, if this bug is kept open, I will
even post an update in it when Philip writes back to tell me that it's
fixed).

Not reproducible, because run-time configurable backtracking/recursion
limits were added in PHP 5.2.0RC1.
Also, PCRE bugs do not belong here, this system is for PHP bugs.

Please test what?  I said that the pcre author knows about the problem,
can replicate it, and that it will someday be fixed, not that it *is*
fixed.

Anyway, I can't run a prerelease version of php -- all of my systems
are in production, so it'll have to wait until php releases a new
version that gets picked up by redhat/fedora.

Description:
------------
This is a rehash/update of Bug #27525
(http://bugs.php.net/bug.php?id=27525), which I can't update (you guys
really need a way for new people to add comments to existing tickets).

Not sure if the original submitter ever emailed Philip, but after
bumping my head against this problem yesterday, I contacted him
myself.

He is now able to reproduce the bug in the current version of pcre
(6.7), and expects to have a fix sometime in september or october (the
first chance he'll have to actually look at the code).  I've created
this new ticket because there will be a pending fix upstream.

fyi, better code to reproduce:

<?php
  $string = str_repeat('x', 11000);
  $pattern = '/(.(?!b))*/';
  echo preg_match($pattern, $string);
?>

And a workaround, since none was posted before:

<?php
  $pattern = '/(.(?!b)){0,540}/';
?>

You can't go above 540 because preg_replace complains about the pattern
being too large.
