      Description

      I started my MariaDB 10.4.8 server as so

      /qa/sw/mariadb/10.4/bin/mysqld --basedir=/opt/krobix/qa/bchin_oakey/mysql/goldDB-10-1570164683 --sql-mode= --sync-binlog=0 --slave-net-timeout=3600 --secure-file-priv= --datadir /opt/krobix/qa/bchin_oakey/mysql/goldDB-10-1570164683/data --port=60477 --max_connect_errors=999999 --server-id=60477 --user=mysql --skip-grant-tables --default-storage-engine=innodb --character-set-server=utf8 --socket /opt/krobix/qa/bchin_oakey/mysql/goldDB-10-1570164683/mysql.sock --innodb_lock_wait_timeout=300 --verbose

      I connected to the server with the following command:

      [root@oak013blue ~]# which mysql
      /usr/bin/mysql
      [root@oak013blue ~]# mysql --version
      mysql Ver 15.1 Distrib 5.5.60-MariaDB, for Linux (x86_64) using readline 5.1
      [root@oak013blue ~]# mysql -u root -h 127.0.0.1 -P 60477

      MariaDB [(none)]> SET GLOBAL `replicate_do_db` = DEFAULT;
      ERROR 2013 (HY000): Lost connection to MySQL server during query
      MariaDB [(none)]> Bye

      here is the trace + other info:

      Server version: 10.4.8-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 = 467735 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

      Trying to get some variables.
      Some pointers may be invalid and cause the dump to abort.
      Query (0x7f0e08012c70): is an invalid pointer

      The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
      information that should help you find out what is causing the crash.

      We think the query pointer is invalid, but we will try to print it anyway.
