      Description

      CREATE TABLE t1 (i INT);
      # For 10.3 the next statement needs to be changed to VALUE(i)
      CREATE TABLE t2 AS SELECT VALUES(i) AS a FROM t1;
      SHOW CREATE TABLE t2;
       
      # Cleanup
      DROP TABLE IF EXISTS t1, t2;

      Reproducible with 5.5-10.3, and also MySQL 5.5; seems to be fixed in 5.6+.
