IT32986: MEMORY LEAK WHEN USING ESQL/C DESCRIBE STATEMENT

APAR status

• Closed as unreproducible.

Error description

• There is a chance of leaking a small amount of memory
  (associated to the internal sql_da structure) when using
  DESCRIBE to get information about fields in a SQL statement.
  The leak will only appear if you use the same prepared statement
  for both DESCRIBE and DECLARE statements like:
  
    sqlcmd = "SELECT * FROM tab1 WHERE pkey = ? AND name = ?";
    EXEC SQL PREPARE :stmt1 FROM :sqlcmd;
    EXEC SQL DESCRIBE INPUT :stmt1 INTO sqlda_input;
    EXEC SQL DECLARE :stmt2 CURSOR FOR :stmt1;
  
  and you free the first statement ('stmt1') first.
