    Description

      Mariadb crashes silently due a segfault, test case, backtrace and config file attached.

      server_config.txt = my.cnf;
      crash_sql.txt = test case, just need to be piped into mysql command line utility;
      crash_log.txt = output with mysqld --verbose, without it mysqld dies without a single line.

      For some strange reason, if the last 2 selects are executed after restarting only the server (but allowing the client to reconnect instead of exiting and entering again) the crash won't happen.
