Crashing the server

CREATE TABLE `t1` ( `c1` char );

SELECT c1 AS ca1 FROM t1 GROUP BY ca1

HAVING ((BIT_AND('6YEgVkuSQ3')) IS NULL) SOUNDS LIKE ((ca1) NOT LIKE (CURRENT_TIMESTAMP)); -- Crash the server

240306 16:33:35 [ERROR] mysqld got signal 11 ;

Sorry, we probably made a mistake, and this is a bug.

Your assistance in bug reporting will enable us to fix this for the next release.

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: 11.5.0-MariaDB source revision: 929c2e06aae47f2dabf51b843ac84911de95bc7f

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 = 468064 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...
