Memory leak when preparing Execute Block which uses domains [CORE4145] #4472
Description
Submitted by: prenosil (prenosil)
Whenever you prepare any of these statements
EXECUTE BLOCK (A RDB$FILE_NAME=?) AS BEGIN END
EXECUTE BLOCK AS DECLARE A RDB$FILE_NAME; BEGIN END
EXECUTE BLOCK AS DECLARE A INTEGER; DECLARE B VARCHAR(255); BEGIN B=CAST(A AS RDB$FILE_NAME); END
you will notice memory leak (e.g. in Windows Task Manager).
(in ISQL it is enough to "execute" the statements with SET PLANONLY ON)
The same statements with type names instead of domain names are o.k., e.g.
EXECUTE BLOCK (A INTEGER=?) AS BEGIN END
