Data table corruption/crashing on btrfs

Creating a DB from a SQL dump (or reading an existing table) is returning various errors - 1877, "cannot open table", or simply segfaulting when a CHECK TABLE command is issued.

This has happened on multiple versions of MariaDB and on multiple machines, including during a SQL dump/restore - in which case the offending table was EMPTY on both the source and destination machine.

Attached is a stack trace and log dump which may be of use.
