Could you please file a bug report at https://mariadb.atlassian.net/secure/Dashboard.jspa?

If it's possible, please include a dump of dTEST.system table (structure and data). If the dump is big or private, you can upload it to our ftp into the private section (ftp://ftp.askmonty.org/private), this way only MariaDB developers will have access to it.

I'll put together a bugreport. I wasn't convinced that I was seeing something that's query-specific, so I decided to simplify matters, and take my current/existing install out of the equation. Doing, instead, a completely NEW drush-install from clean Drupal source, after a clean/new install of MariaDB *and* it's datadir&files, I see the SAME error, on mutliple queries: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away If you can re-suggest what info to include, given what I've included below, I'll get that bug report put together.
