On a debug build with ASAN (on some reason only with ASAN) the test case causes an assertion failure:

Reproducible on 10.3-10.5.
Non-ASAN builds of 10.3-10.5 and any builds of 10.1-10.2, as well as MySQL 5.6/5.7/8.0, don't crash, but they return the empty result set:
SELECT * FROM t1 WHERE IFNULL(b, DEFAULT(a)) IS NOT NULL; |
a b
|
DROP TABLE t1; |
This seems to be wrong, because IFNULL(b, DEFAULT(a)) IS NOT NULL is clearly true:
SELECT IFNULL(b, DEFAULT(a)) IS NOT NULL FROM t1; |
IFNULL(b, DEFAULT(a)) IS NOT NULL |
1
|
1
|
Also, if DATETIME is replaced with TIMESTAMP in the same case, then the result set is returned:
CREATE TABLE t1 (a TIMESTAMP DEFAULT CURRENT_TIMESTAMP, b INT); |
INSERT INTO t1 () VALUES (),(); |
SELECT * FROM t1 WHERE IFNULL(b, DEFAULT(a)) IS NOT NULL; |
a b
|
2019-12-30 02:23:13 NULL |
2019-12-30 02:23:13 NULL |
DROP TABLE t1; |
Finally, here is a variation of the test case which causes the same assertion failure on 10.3 and 10.5 ASAN builds, but a different one on 10.4 ASAN build. The change in the test case is the absence of IS NOT NULL in the WHERE clause:
CREATE TABLE t1 (a DATETIME DEFAULT CURRENT_TIMESTAMP, b INT); |
INSERT INTO t1 () VALUES (),(); |
SELECT * FROM t1 WHERE IFNULL(b, DEFAULT(a)); |
|
|
# Cleanup
|
DROP TABLE t1; |
