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.
