This is an internal tokudb assertion.
I'd say it's *very* unlikely that anything we've done in MariaDB
could've caused this assertion.
But MariaDB-5.5.41 included tokudb-7.5.3, and MariaDB-5.5.44 included
tokudb-7.5.7. It's quite possible that some tokudb change between 7.5.3
and 7.5.7 is the reason.
