Hi,

System:
FreeBSD 6.2
Wordpress 2.1.1
Apache13+modssl+mod_mysql
PHP 5.2.1 with Suhosin-Patch 0.9.6.2 (cli)
mysql 5.0.33

Problem:
While clicking around on / browsing my Site, every once in a while a Pages / Posts content does not finish loading, and i get the below error in my apache log.

[Wed Feb 28 14:29:36 2007] [error] PHP Warning: preg_replace() [<a href='function.preg-replace'>function.preg-replace</a>]: Compilation failed: lookbehind assertion is not fixed length at offset 10 in /wp-includes/formatting.php on line 76

Does anyone else have this Issue?

Thanks a lot,

I also have this problem on FreeBSD6.2 amd64 and i386, Apache 2.2.4 with php5.2.1_3, it did not show up with php5.2.1_2 or php5.2.1_1.

This has been resolved as bogus, in my opinion.
It turned out the php5-pcre port on FreeBSD had some library compatibility problems (whatsoever), which would turn up in rare circumstances when using pcre with utf-8 strings, escpecially with lookbehind or readahead assertions.
My workaround was to use nl2br for that part in the pee-function that uses lookbehind for inserting <br />s. But after all, recompiling a newer fixed port version of php5-pcre made the problems go away.
