Queries like: SELECT ROW(1, 2) IN (SELECT t1.a, 2) FROM t1 GROUP BY t1.a or SELECT ROW(1, 2) IN (SELECT t1.a, 2 FROM t2) FROM t1 GROUP BY t1.a lead to assertion failure in the Item_in_subselect::row_value_transformer method in debugging build, or to unexpected error message in release build: ERROR 1247 (42S22): Reference '<list ref>' not supported (forward reference in item list) Unexpected error message and assertion failure have been eliminated.

Noted in 5.0.60, 5.1.24, 6.0.5 changelogs. Queries such as SELECT ROW(1, 2) IN (SELECT t1.a, 2) FROM t1 GROUP BY t1.a (combining row constructors and subqueries in the FROM clause) could lead to assertion failure or unexpected error messages.
