      Description

      A split from MDEV-6083. Please note that 5.5 is also affected, just comment out assertion in intern_sys_var_ptr().

      # It's not necessary to install TokuDB at runtime, 
      # instead the server can be run with --plugin-load=ha_tokudb
       
      INSTALL SONAME 'ha_tokudb';
      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a INT) ENGINE=TokuDB;
      INSERT INTO t1 VALUES (1),(2);
      UNINSTALL SONAME 'ha_tokudb';
       
      # Let server to shutdown (with MTR, it happens on its own)
