If you get any error message stating something like Parsing Error, it is probably not the error returned by Firebird, but rather the admininstration tool you're using. Some of the tools (like IBExpert or EMS) try to be smart and parse your statements before they even get to Firebird. However, they do it incorrectly some of the time, as the parsers are not generic and often choke on new Firebird features. So, make sure you use some tool with generic parser (isql or FlameRobin) before reporting bugs to Firebird team. And always use the latest available version of your tool as the bug is probably already detected by other users and fixed.
