 Description   

PoC:

CREATE TEMPORARY TABLE v0 ( v1 INT DEFAULT ( from_unixtime ( LAST_DAY ( CASE 0 WHEN 'x' THEN 'x' ELSE 'x' END ) ) ) ) ;
 
 UPDATE v0 SET v1 = '' WHERE v1 IS NULL ;
 
 INSERT INTO v0 ( ) VALUES ( NVL ( FALSE , EXP ( ( 'x' | 'x' ) ) ) , POINT ( ( NOT time_to_sec ( NULL ) ) , 90700366.000000 ) ) ;

crash log:

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: 10.7.0-MariaDB
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=1
max_threads=153
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467956 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x62b0000bd218
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...
