    Description

      step to reproduce:

      CREATE TABLE v0 ( v1 SERIAL ) AS SELECT BINARY 'x' v1 HAVING ( AVG ( DISTINCT ( v1 BETWEEN 62 + 91854449.000000 AND 43 ) ) ) * 2147483647 ;
       SELECT v1 FROM v0 LIMIT 58 ;
       CHECK TABLE v0 . v1 ;
       ALTER TABLE v0 ADD COLUMN ( DATE INT DEFAULT ( DEFAULT ( v3 ) ) , v3 INT DEFAULT ( GeomFromText ( addtime ( -128 - 55 , 'x' ) ) ) UNIQUE , v2 DATETIME ) ;
       SELECT COUNT ( * ) FROM v0 FORCE INDEX ( PRIMARY ) ;
      

      report (compiled with ASAN):

      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.

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