Not a solution but a workaround if you are not using the positions is to call 
the parser with:

$parser->parse($sql);

The problem occurs, because "null" is set as operator, it should be set to 
constant. Let me look into the code...

Check out REV 299, it should work now. Plz check your client code, the NULL 
keyword is no longer an "operator", it is now a "constant".

I tested the original query with REV 300 and it works as expected.

Thank you.
