Assertion `!(index->table)->not_redundant()' failed in row_log_table_low_redundant

    Details

      Description

      The test case is non-deterministic, as it has a send. It fails on the 1st attempt for me, but it can vary on different machines/builds. Run with --repeat=N if it doesn't fail right away.

      --source include/have_innodb.inc
       
      CREATE TABLE t1 (f INT NOT NULL) ENGINE=InnoDB;
      INSERT INTO t1 VALUES (1);
      ALTER TABLE t1 MODIFY COLUMN f INT NULL DEFAULT NULL;
       
      --connect (con1,localhost,root,,test)
      --send
        OPTIMIZE TABLE t1 ;
       
      --connection default
      INSERT INTO t1 VALUES (2),(3),(4),(5);
      INSERT INTO t1 VALUES (6),(7),(8),(9);
       
      # Cleanup
      --connection con1
      --reap
      --disconnect con1
      --connection default
      DROP TABLE t1;
