Columnstore throws rows with union all and subselect with null in select and impossible where condition

To reproduce:

drop table if exists t1col;

drop table if exists t1inno;

create table t1col (id int) engine=columnstore;

create table t1inno (id int) engine=innodb;

select * from

(

Select ID

FROM

(

SELECT 1 ID

FROM 

t1col

) V

UNION ALL

SELECT ID

FROM

(

SELECT NULL ID WHERE 1=0

) V

) U;

select * from

(

Select ID

FROM

(

SELECT 1 ID

FROM 

t1inno

) V

UNION ALL

SELECT ID

FROM

(

SELECT NULL ID WHERE 1=0

) V

) U;

Result with innodb table:

Empty set (0.001 sec)

Result with Columnstore table:

------

------

------
1 row in set (0.043 sec)

Columnstore throws the same result like innodb, if

• change "where 1= 0" to "where 1=1" (or without where condition)
• change SELECT NULL ID to SELECT 1 ID
• Remove the outer wrapper "select * from (...."
