    Description

      _The assertion is similar to MDEV-31215 but the stack is different and the crash is reproduced on 10.5+ debug builds _

      SET character_set_connection=ucs2;
      CREATE TABLE t1 (d1 date not null, d2 date, gd text as (concat(d1,if(d1 <> d2, date_format(d2, 'to %y-%m-%d '), ''))) );
      --ERROR ER_NO_SUCH_TABLE
      SELECT (SELECT 1 FROM foo) FROM t1;
      INSERT INTO t1 (d1) VALUES ('2009-07-02');
      

      Leads to:
