Server crash or ASAN use-after-poison in Query_arena::free_items after executing a failing PS which reads from versioned table

    Details

      Description

      Note: I don't know why versioning is important here, but I couldn't get rid of it, neither by adding invisible columns nor virtual columns nor both, while with system versioning it happens regardless it's timestamp- or trx-based, explicit or implicit, InnoDB or MyISAM.

      CREATE TABLE t1 (a INT) WITH SYSTEM VERSIONING;
       
      PREPARE stmt FROM "CREATE TABLE tmp AS SELECT * FROM t1 WHERE EXP(20010609211642053929)";
      --error ER_DATA_OUT_OF_RANGE
      EXECUTE stmt;
       
      # Cleanup
      --connection default
      DROP TABLE t1;
      

      10.3 ASAN 99fa7c6c2f9c
