Assertion `!(((trx))->auto_commit && ((trx))->will_lock == 0)' failed in lock_table_create upon reading from locked InnoDB sequence

    Details

      Description

      Note: the scenario is very similar to MDEV-13015, so it might be a duplicate; but the assertion failure is different, so I'm filing it just in case.

      --source include/have_innodb.inc
       
      create sequence s1 engine=InnoDB;
      --source include/restart_mysqld.inc
      lock table s1 read;
      select * from s1;
       
      # cleanup
      unlock tables;
      drop sequence s1;
