[GPU Logic Bug] SELECT /*+ keep_table_function_result */ <column> FROM <table> GROUP BY <column> Brings Errors

[qwebug]

Describe:

SELECT /*+ keep_table_function_result */ <column> FROM <table> GROUP BY <column> brings different results, when using CPU-only configurations and GPU-used configurations.

SQL with CPU-only Config:

CREATE TABLE t0(c0 bigint);
INSERT INTO t0(c0) VALUES(1);
INSERT INTO t0(c0) VALUES(2);
INSERT INTO t0(c0) VALUES(NULL);
ALTER SESSION SET EXECUTOR_DEVICE='CPU';
SELECT /*+ keep_table_function_result */  t0.c0 FROM t0 ORDER BY t0.c0 DESC;

Result:

c0
NULL
2
1

SQL with GPU-used Config:

ALTER SESSION SET EXECUTOR_DEVICE='GPU';
SELECT /*+ keep_table_function_result */  t0.c0 FROM t0 ORDER BY t0.c0 DESC;

Result:

c0
1
2
NULL
