Assertion `bit < (map)->n_bits' failed in bitmap_is_set

    Details

      Description

      Notes:

      • the test case has seemingly nothing to do with versioning, but it only fails on bb-10.3-temporal (and on tempesta-tech/mariadb), so I suppose it's related to some new code introduced in the tree (hence the regression label);
      • recently there the same assertion failure MDEV-13719 fixed for replication scenario. The fix naturally does not help for this case, but maybe it give the idea.

      CREATE OR REPLACE TABLE t1 (pk int) ENGINE=InnoDB PARTITION BY RANGE(pk) (PARTITION p1 VALUES LESS THAN (1), PARTITION p2 VALUES LESS THAN (3));
      LOCK TABLE t1 WRITE;
      --error ER_SAME_NAME_PARTITION
      SET STATEMENT lock_wait_timeout=5 FOR ALTER TABLE t1 ADD PARTITION (PARTITION p1 VALUES LESS THAN (1));
      SELECT * FROM t1;
       
      # Cleanup
      DROP TABLE t1;
