We've came across this message when using 2.5 and we thought that it is because of the SQL statement size limit.
But we still see it in 3.0 (http://www.firebirdfaq.org/faq197/
And we get this message executing statements with length less than 64k.
We've tried to reproduce such behavior on a test example and came to conclusion,
that the error is rased when you combine using IN operator and select statement from a table with large number of indicies.
It is very strange, so we created test example with one table and 20 indicies and got an error when selecting non indexed field from the table.
If we decrease the number of indicies then the error will disapear.
