Hi Jamie,Yes, please file a bug at https://mariadb.atlassian.net/secure/Dashboard.jspa. We have a few bugs with wrong results currently in work, but I can't find right away any that matches your scenario.

Hi Folks,
I'm seeing a difference in a query result between MariaDB 5.5.32 and
MySQL 5.1.69.
I've distilled things down as far as I can get them, while still being
able to reproduce the issue. Anything else I do to get the sample to
make it smaller or more focused seems to make the issue disappear.
The data: https://www.dropbox.com/s/m02sqjl2y2cq4ky/sampledump1.zip
The query, and the results (and explains) in both MySQL and MariaDB:

What's going on here? Is there an oustanding bug for this? Should I file
a bug?
As a workaround, please try
set optimizer_switch='derived_merge=off';
Regards,
Elena
Thanks,
Jamie
