Description
OOB assertion failed in debug version of MariaDB.
POC:
—
CREATE TABLE v0 ( v1 INT ) ; |
INSERT INTO v0 ( v1 ) VALUES ( 2 ) ; |
UPDATE v0 SET v1 = 68 WHERE v1 = -128 ; |
INSERT INTO v0 ( v1 ) VALUES ( -32768 ) , ( -128 ) ; |
CREATE VIEW v3 ( v4 , v5 ) AS SELECT * FROM v0 , v0 WINDOW v2 AS ( PARTITION BY 24 , -1 , 18 , 0 ORDER BY v1 DESC ) ; |

Stack dump:
—
mysqld: /home/mysql/mariadb/sql/sql_array.h:65: Element_type &Bounds_checked_array<Item *>::operator[](size_t) [Element_type = Item *]: Assertion `n < m_size' 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.

|
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...
