      Description

      I'm not sure at all that the failure has anything to do with RANDOM_BYTES, but it's the first time I've ever seen it, and I can't find anything to replace RANDOM_BYTES with to make the test applicable to other branches. Please reduce the priority if the analysis shows it's unrelated.

      CREATE TABLE t (a INT);
      INSERT INTO t VALUES (1),(2);
      SELECT RANDOM_BYTES(CAST('-00:00:10' AS TIME)) f1, IFNULL(a,1) f2 FROM t GROUP BY f1, f2;
       
      # Cleanup
      DROP TABLE t;
