MariaDB Server SEGV issue

CREATE TABLE v0 ( v1 TIMESTAMP ) ;

 OPTIMIZE TABLE v0 ;

 CHECK TABLE v0 . v1 ;

 ALTER TABLE v0 ADD COLUMN v0 TEXT CHAR SET ASCII DEFAULT ( v1 + DEFAULT ( v1 ) ) ;

 DESCRIBE SELECT DISTINCT v0 . v1 FROM ( SELECT * FROM v0 ) v0 ;

 CREATE TABLE v3 ( v2 INT ) PARTITION BY LIST ( v1 ) ( PARTITION v0 VALUES IN ( 8 ) ) ;

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.

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...
