Description
One of our customers reported that the execution of stored procedure involving "CONNECT"/"MEMORY" engine tables, table_type=WMI, CTE, JOIN, UNION ALL QUERY, causing MariaDB server running on Windows platform to crash.
I can locally able to reproduce the crash, at 10.4.17 (customer version) and 10.5.9 (latest release).
Repro Steps:
1. Install MariaDB server 10.4.17/10.5.9 at the Window Machine.
2. Install connect plugin.
3. Restore the dump file - proc_monitor_values_prtg_new.sql
4. call the procedure - server_monitoring.query_monitor_values_prtg.
call server_monitoring.query_monitor_values_prtg;
First time execution, will work. 2nd time it will crash the server.

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: 10.5.9-MariaDB
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=2
|
max_threads=65537
|
thread_count=2
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 136467 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went

terribly wrong...
