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...
