Strange!

I tried it with and without the PARTITION BY clause and it crashed the
service either way.

Took out ROW_NUMBER() and it ran fine.

FWIW, the query runs just fine as is in SQLite.

Edit: I found similar bug reports in jira.mariadb.org, but they're all
closed. So I created a new bug report.

I would recommend you to use the WSL feature if you can't use a Unix or
Unix like OS.

WSL allows you to run the Linux binaries, far more stable and I would
recommend that for other enterprise tools as redis, kafka, apache,
nginx, and so on.

I doubt it.

It's WAMP (Windows Apache MariaDB Python) for me, if I go that route.

Didn't find that many MacOS users reporting something, but that may have
to do with few of them run on that OS.

You won't know until you tried.

Did you check the log file ?

(see: `show variables like 'log_error';`)
