      CREATE TEMPORARY TABLE t1 (a INT) ENGINE=InnoDB;
      CREATE TEMPORARY TABLE t2 (b INT, c INT) ENGINE=InnoDB ROW_FORMAT=COMPACT;
      LOCK TABLE t2 WRITE;
      ALTER TABLE t2 DROP COLUMN c;
      CREATE OR REPLACE TEMPORARY TABLE t1 (d INT) ENGINE=InnoDB ROW_FORMAT=COMPRESSED;
      

      Reproducible on older 10.2 builds too.
      First noticed some time around MDEV-10813 development.
      No visible problems on non-debug builds.
