Description
The following test case causes an assertion failure in Debug build of the current 10.3 and most probably of all other versions:
create table t1 (a int);
|
insert into t1 values (3), (2);
|
create table t2 (b int);
|
insert into t2 values (4), (2);
|
create table t3 (c int);
|
insert into t3 values (7), (1);
|
|
|
select a from t1
|
where a >= any (select b from t2 group by (select c from t3 where c = 1));
|
|
|
drop table t1,t2,t3;
|
The failure happens in item_subselect.cc():
