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.

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