LOG INFORMATION:

mysqld: /data/src/ce/stonedb/sql/sql_optimizer.cc:5286: bool JOIN::init_planner_arrays(): Assertion `primary_tables == 0 && tables == 0' failed.

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=536870912
read_buffer_size=4194304
max_used_connections=1
max_threads=100
thread_count=1
connection_count=1
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1344870 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

How To Reproduce

 CREATE TABLE `t_test` (
  `id` int(11) NOT NULL,
  `first_name` varchar(10) NOT NULL,
  `last_name` varchar(10) NOT NULL,
  `sex` varchar(5) NOT NULL,
  `score` int(11) NOT NULL,
  `copy_id` int(11) NOT NULL
) ENGINE=TIANMU DEFAULT CHARSET=utf8mb4

SELECT
	bb.first_name,
	bb.last_name 
FROM
	(
SELECT
	count( distinct a.first_name ) AS first_name,
	a.last_name AS last_name 
FROM
	t_test a,
	t_test b 
WHERE
	a.id = b.id 
GROUP BY
	a.last_name
