      Description

      step to reproduce:

      CREATE TABLE v0 ( v1 DECIMAL UNIQUE CHECK ( CASE 0 * 27302337.000000 WHEN 34 THEN + 'x' LIKE 'x' OR v1 NOT IN ( -1 / TRUE ^ 2 ) ELSE 7105743.000000 END ) ) ;
       INSERT INTO v0 VALUES ( 90 ) , ( -1 ) , ( 31152443.000000 ) , ( -32768 ) , ( NULL ) , ( NULL ) ;
       INSERT INTO v0 SELECT AVG ( 'x' ) OVER ( PARTITION BY ( ( NOT AVG ( 76698761.000000 ) ) ) IS NOT NULL ) ;
       INSERT IGNORE INTO v0 ( ) VALUES ( 0 ) , ( 'x' ) , ( 3751286.000000 ) , ( 'x' ) , ( ( v1 = 'x' AND 0 AND 0 ) ) ;
       INSERT INTO v0 VALUES ( 127 ) ;
       INSERT INTO v0 SELECT -2147483648 END FROM v0 AS TEXT JOIN v0 JOIN v0 TABLES ;
       ALTER TABLE v0 ADD ( v2 INT UNIQUE CHECK ( ( v1 = 'x' AND ( ( - ( + ( BINARY 49730460.000000 ) ) ) ) = 'x' BETWEEN 'x' AND 'x' ) ) ) ;
       UPDATE v0 SET v1 = -128 WHERE v1 IS NULL ORDER BY 78 IN ( 'x' , 'x' ) , v1 ;
      

      report (compiled with ASAN):

      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.

      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.

      where mysqld died. If you see no messages after this, something went
      terribly wrong...
