This problem is unrelated to Drupal code, but is triggered by Drupal's use of core PHP functions that have not been compiled correctly on some servers.

This is a bug in your server environment not executing the PCRE (Perl Compatible Regular Expressions) module for PHP correctly.

Depending on the server environement, there are several different causees (including a reported bug in some versions of PHP 5).

In our case, an upgrade of RedHat included a bad library and required a patch.

Send the content of the error to your system admin and have them debug your PHP's PCRE module.
