| * | MDEV-7339 Server crashes in Item_func_trig_cond::val_int | Sergei Golubchik | 2017-07-12 | 1 | -0/+6 |
| | | | | | | | | | | | | | | | | | Item_in_subselect::pushed_cond_guards[] array is allocated only when left_expr->maybe_null. And it is used (for row expressions) when left_expr->element_index(i)->maybe_null. For left_expr being a multi-column subquery, its maybe_null is always false when the subquery doesn't use tables (see Item_singlerow_subselect::fix_length_and_dec() and subselect_single_select_engine::fix_length_and_dec()), otherwise it's always true. But row elements can be NULL regardless, so let's always allocate pushed_cond_guards for multi-column subqueries, no matter whether its maybe_null was forced to true or false. | ||||
