Description
The problem is reproducible very unreliably, sometimes it's fast, sometimes it takes hundreds of repetitions. Luckily, the test is short. Run with --repeat=1000.
Make sure that your plugin directory is populated. It might have something to do with TokuDB in general or MDEV-15174 in particular – I can't get the failure without ha_tokudb in the plugin directory.
The test case (and bug report) is for 10.3, because I couldn't get rid of INTERSECT in the scenario. Maybe when the reason is known, it will be possible to reproduce with the syntax applicable to previous versions.
