Description
There was a similar bug MDEV-5284, but it's fixed and the fix is merged into 10.0, while the test case below still fails (only on 10.0 for me).
sql/opt_subselect.cc:1314: bool replace_where_subcondition(JOIN*, Item**, Item*, Item*, bool): Assertion `!do_fix_fields || !(*expr)->fixed' failed.

SET optimizer_switch='semijoin=on'; |
|
CREATE TABLE t1 (a INT, b INT) ENGINE=MyISAM; |
INSERT INTO t1 VALUES (1,2),(3,4); |
|
CREATE VIEW v1 AS SELECT * FROM t1 WHERE a IN ( SELECT b FROM t1 ); |
|
SELECT * FROM t1 INNER JOIN v1 ON ( v1.a = t1.a OR v1.b > 0 ); |
Also fails with a subquery instead of a view (in this case derived_merge=on is also neede).
