 After update from WP 4.1.4 to 4.1.2 at PHP 5.5.0. I got this error:

 Warning: preg_replace(): Compilation failed: repeated subpattern is too
 long at offset 592 in /home/www/xxxxxx/html/www.xxxxxx.com/blog/wp-
 includes/wp-db.php on line 2640

 I found a workaround here:
 http://forum.wpde.org/installation/142182-nach-update-auf-4-2-1-keine-
 umlaute-mehr-speicherbar-2.html#post614130

 After disabling this line in wp-db.php it is working again.
 {{{
 // $value['value'] = preg_replace( $regex, '$1', $value['value'] );
 continue;
 }
 }}}

 Kind regards,
 Marcus
