mysqltest: At line 29: query 'SELECT * FROM t' failed: <Unknown> (2006): Server has gone away

The result from queries just before the failure was:
< snip >
INSERT INTO t VALUES(2);
DELETE FROM t WHERE a=2;
connection default;
# Normal MariaDB shutdown would roll back the above transaction.
# We want the transaction to remain open, so we will kill the server
# after ensuring that any non-transactional files are clean.
FLUSH TABLES;
# Ensure that the above incomplete transaction becomes durable.
SET GLOBAL innodb_flush_log_at_trx_commit=1;
BEGIN;
INSERT INTO t VALUES(0);
DELETE FROM t WHERE a=0;
COMMIT;
# restart: --innodb-force-recovery=3
disconnect con1;
SELECT * FROM t;
