PCRE Problems

[Fluke667]

After upgrading php to 5.3.10 via EasyApache (cPanel) there is a problem with my vBulletin 3.8.7...

This is the Error:

Warning: preg_replace() [function.preg-replace]: Compilation failed: lookbehind assertion is not fixed length at offset 684 in [path]/includes/functions_newpost.php (Line 260)

It looks like a Bug in PCRE:

How to Downgrade this PCRE thing back to 8.20 ?
