Description
If I run this store procedure twice in a row in the same session, the server will crash with Signal 6.
CREATE DEFINER = 'leo'@'%'

PROCEDURE PlayGround.procedure2()
|
BEGIN
|
|
Select
|
(Select Sum(`TestCase`.Revenue) From PlayGround.Anything E
|
Where TestCase.TemplateID not in (Select 1 from PlayGround.Anything where 2=2)
|
) As `ControlRev`
|
From
|
(Select 3 as Revenue, 4 as TemplateID) As `TestCase`
|
Group By TestCase.Revenue, TestCase.TemplateID;
|
|
END
|
PlayGround.Anything table is an empty table with only one primary key field `ID`, and it doesn't really have to do anything, it could be any table even mysql.slow_log. The content of the SP may look strange, but I was try to simplify my product SP to create a test case.
Here is the log
pure virtual method called

|
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.
|
|

|
|
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: 10.0.15-MariaDB-wsrep-log
|
key_buffer_size=524288
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=501
|
thread_count=11
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 525444581 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...
