LP:534626 - MyISAM table created in MariaDB not readable by MySQL

I created a simple table in MariaDB and then when I tried to access it in MySQL, the table is reported as damaged and can't be repaired.

Versions used were 5.1.42 of each on Linux x86.

Script:

In MariaDB:

use test;
CREATE TABLE t1 (a char(100), b int) ENGINE=myisam;
INSERT INTO t1 values ('aaaa', 10);
SELECT * FROM t1;

Shutdown MariaDB and point MySQL at the same datadir.

In MySQL:

use test;
SELECT * FROM t1;
REPAIR TABLE t1;

Errors from MySQL:

mysql> select * from t1;
ERROR 1035 (HY000): Old key file for table 't1'; repair it!
mysql> repair table t1;
