Many Issues with PHP 5.2 and WordPress are related to the new php that works pretty bad with system pcre library. Instead of fixing this, the php dev team just says “please, use embeded version…” they think that this is a good fix but its really just duct taping things together. Php needs to be rebuilt, it should use embeded pcre library instead of system one during compiling. If you need some professional help with this duct tape, contact yourserveradmin.com
