    Details

      Description

      Looks like a new occurrence of MDEV-26453

      CREATE TABLE t2 (a INT,b CHAR(20)) ENGINE=InnoDB;
      CREATE UNIQUE INDEX bi USING HASH ON t2 (b);
      INSERT INTO t2 VALUES (0,0);
      SET sql_mode='pad_char_to_full_length';
      DELETE FROM t2;
      

      Leads to:
