ESQLC prepare/execute/free causes memory leak on server

Is anyone aware of problems with ESQL/C (7.?) causing a memory leak in Online (7.12 -> 7.23) by not freeing memory off following a calling to $FREE. A typical scenario might be: $CHAR col2val[10]; for (i = 0; i < 1000; i++) { $PREPARE p1 FROM SELECT * from table where col1 > 'A' and col2 = ?; $DECLARE c1 CURSOR WITH HOLD FOR p1; $EXECUTE c1 USING $col2val; $FETCH c1 INTO .....; $CLOSE c1; $FREE p1; }
