Description
We found an assertion fail that crash debug version of MariaDB.
POC:
—
CREATE TABLE v0 ( v1 INT ) ; |
INSERT INTO v0 ( v1 ) VALUES ( 9 ) ; |
UPDATE v0 SET v1 = 2 WHERE v1 IN ( SELECT v1 WHERE v1 = v1 OR ( v1 = -1 AND v1 = 28 ) ) ; |
INSERT INTO v0 ( v1 ) VALUES ( 60 ) , ( 0 ) ; |
SELECT RANK ( v1 ) OVER w , STD ( v1 ) OVER w FROM v0 WINDOW v2 AS ( PARTITION BY v1 ORDER BY v1 * 0 ) ; |

Stack dump:
—
mysqld: /home/mysql/mariadb/sql/item_subselect.cc:2273: bool Item_in_subselect::create_single_in_to_exists_cond(JOIN *, Item **, Item **): Assertion `false' failed.

|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

Server version: 10.5.3-MariaDB-debug

key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=2
|
max_threads=153
|
thread_count=3
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467925 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went

terribly wrong...
