Additionally execution of "select ? + 1 from t" produces zeros regardless of parameter values passed.

Description: Execution of prepared statement "SELECT ?, {whatever}" with NULL as corresponding parameter produces wrong output. The problem occurs only when "?" is directly in the output list: "SELECT ?" produces wrong results while "SELECT ?+1" or produces correct result. How to repeat: Prepare statement "SELECT ?". Execute it with integer NULL as parameter. Get -214783648 as result.
