Problem was that if copy_data_between_tables() didn't do proper clean up in case of failures: - copy object was not properly freed - end_bulk_insert() was not called - mysql_trans_prepare_alter_copy_data() set THD->transaction.on to false which was not properly restored The last part caused a crash in Aria as Aria depends on that THD is correct. Other things: - Reset info->switched_transactional after usage (safety) - Reset bulk_insert_single_undo (safety)
