      Description

      Note: The test is non-deterministic, run with --repeat. It fails for me within 10 attempts, but it can vary on different machines. ASAN or Valgrind don't help.

      --source include/have_partition.inc
       
      CREATE TABLE t1 (pk INT PRIMARY KEY) ENGINE=MyISAM WITH SYSTEM VERSIONING;
      INSERT INTO t1 VALUES (11),(12);
      ALTER TABLE t1 PARTITION BY KEY() PARTITIONS 3;
      DELETE FROM t1 WHERE pk >= 0;
       
      # Cleanup
      DROP TABLE t1;
      

      10.3 9d97e6010eb

      mysqltest: At line 6: query 'DELETE FROM t1 WHERE pk >= 0' failed: 126: Index for table './test/t1#P#p1.MYI' is corrupt; try to repair it
      

      Also reproducible with Aria. Could not reproduce with InnoDB.
