The problem was overflow in max_length when we tried to des_decrypt() something which is not the output of des_encrypt() mysql-test/r/ssl_and_innodb.result: New test case. mysql-test/t/ssl_and_innodb.test: New test case. sql/item_strfunc.h: Do not subtract the encrypt overhead (9U) if args[0] has length < 9 (In unsigned arithmetic, (1-9) becomes a very large number)
