LP:825035 - Wrong result on second execution of a prepared outer join with empty table

If one of the operands of an outer join is an empty table, the second execution as a prepared statement returns no rows.

explain:

id select_type table type possible_keys key key_len ref rows Extra
1 SIMPLE t1 system NULL NULL NULL NULL 0 const row not found
1 SIMPLE t2 ALL NULL NULL NULL NULL 4

test case:

CREATE TABLE t1 (a int);

CREATE TABLE t2 (a int);
INSERT INTO t2 VALUES (1),(2),(3),(4);

CREATE PROCEDURE sp1 ()
SELECT *
FROM t2
LEFT JOIN t1 ON t1.a = t2.a ;

CALL sp1();
CALL sp1();

Reproducible with maria-5.3. Not reproducible with maria-5.2, mysql-5.5. This bug prevents further testing of subqueries in a prepared statement context.
