Apparently it's a leftover from bug#901506.
Now the additional condition is that max_join_size is set to a non-default value. In the test case it's unrealistically small, but in fact the threshold depends on the number of rows in t2. 20 rows was as low as I could reach still getting the crash, and it requires the max size value of ~ 80. A more complicated test case with ~300 rows in the table was still causing the crash with max_join_size=1,000,000.

The SELECT itself fails with ER_TOO_BIG_SELECT.

Minimal optimizer_switch: materialization=on,semijoin=on (both are defaults)

Test case:

INSERT INTO t1 VALUES (1),(2);
INSERT INTO t2 VALUES
(1),(2),(3),(4),(5),
(6),(7),(8),(9),(10),
(11),(12),(13),(14),(15),

SET optimizer_switch = 'materialization=on,semijoin=on';
SET max_join_size = 80;
