I can confirm this is happening, but I also get a crash with the select rather than just update.
Unable to modify the SQL 'NOT' to give a crash - which is what I would probably expect since only the number of parameters matter not how they are used.
Firebird 2.0 and PHP5.2.5

I beg pardon. I was, probably, inattentive. SELECT query PHP crash too.
PHP 5.2.6 FIREBIRD 2.1.0
