Reported By: kaiser at macbureau dot de
Status: No Feedback
Bug Type: PCRE related
Operating System: FreeBSD 7
PHP Version: 5.2.6
New Comment:
This is still broken. FreeBSD 7.1 and PHP 5.2.9. It seems that the
original bug filer has provided plenty of repro. If that is not the
case
I'd be happy to go through the process of digging up all I can from my
machine.

Got the same bug, PHP 5.2.8/PCRE 7.8, Apache 2.2.11, Freebsd.

I have a similar problem after upgrading to PHP 5.2.8/PCRE 7.8 on a
FreeBSD 7.1/amd64. I'm trying to upgrade Gallery2 to 2.3 and the
installer fails with that error.

We are also having this problem on FreeBSD 7 with Apache 1.3. The
stack trace is the same:

(This version was built with the FreeBSD PCRE instead of the builtin
in case that helped; it didn't.)
In one case, a customer has to set pcre.backtrack_limit and
pcre.recursion_limit to 10 to get a Wordpress RSS feed to load.
Are those considered "sane" values?
Or is this getting ignored due to the incorrect "No Feedback" status?
