      Description

      Hi!

      The following query crashes a freshly installed 10.3.27 server:

      SELECT DISTINCT m_u.user, m_u.host
          FROM mysql.user m_u
          LEFT JOIN performance_schema.accounts ps_a
            ON m_u.user = ps_a.user AND ps_a.host = m_u.host
          LEFT JOIN information_schema.views is_v
            ON is_v.DEFINER = CONCAT(m_u.User, '@', m_u.Host) AND is_v.security_type = 'DEFINER'
          LEFT JOIN information_schema.routines is_r ON is_r.DEFINER = CONCAT(m_u.User, '@', m_u.Host) AND is_r.security_type = 'DEFINER'
          LEFT JOIN information_schema.events is_e ON is_e.definer = CONCAT(m_u.user, '@', m_u.host)
          LEFT JOIN information_schema.triggers is_t ON is_t.definer = CONCAT(m_u.user, '@', m_u.host)
          WHERE ps_a.user IS NULL
            AND is_v.definer IS NULL
            AND is_r.definer IS NULL
            AND is_e.definer IS NULL
            AND is_t.definer IS NULL
          ORDER BY m_u.user, m_u.host;
      

      Stack trace is:

      10209 17:35:12 [ERROR] mysqld got signal 11 ;
      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.
       
      Server version: 10.3.27-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=1
      max_threads=153
      thread_count=7
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467424 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...
