Problem was that SQL level tried to read a record with rnd_pos() that was already deleted by the same statement.
In the case where the page for the record had been deleted, this caused an assert.
Fixed by extending the assert to also handle empty pages and return HA_ERR_RECORD_DELETED for reads to deleted pages.
Still reproducible:
