    Description

      Note: The test case is similar to MDEV-20497 and MDEV-20338. The main difference is that till recently it didn't crash, but returned unexpected success on 2nd execution (see below). Starting from revision 33f55789 (MDEV-18727 improve DML operation of System Versioning) it also crashes.

      CREATE TABLE t1 (a INT);
      CREATE PROCEDURE pr() UPDATE t1 FOR PORTION OF app FROM '2019-07-16' TO '2019-12-14' SET a = 1;
      --error ER_PERIOD_NOT_FOUND
      CALL pr;
      --error ER_PERIOD_NOT_FOUND
      CALL pr;
       
      # Cleanup
      DROP PROCEDURE pr;
      DROP TABLE t1;
