Bug in :SIZE of EXEC SQLs ?

Is there a known problem in ProFORTRAN/ProC EXECs like:

     EXEC SQL FOR :SIZE EXECUTE statement USING DESCRIPTOR d

whereby the statement actually executes one more time than it should? The particular problem is on INSERTs using dynamic SQL method 4. The data for the insert comes from host arrays, and the very first record (the one whose data comes from the first elements of the bound arrays) seems to get inserted twice. (All the others are inserted correctly).
