    Details

      Description

      Whilst there are many other bugs with the same assertion, this one looked new/unrelated. Issue reproduces on all engines tested. MDEV-18166 (testcase 2) and MDEV-19680 may be related

      USE test;
      CREATE TABLE t (a INT, b INT DEFAULT (a+1));
      INSERT INTO t VALUES (1,1);
      UPDATE t SET b=DEFAULT;
      

      Leads to:
