1 error[E0038]: the trait `X` cannot be made into an object
2 --> $DIR/issue-67510-pass.rs:7:23
4 LL | fn _func1<'a>(_x: Box<dyn X<Y<'a>=&'a ()>>) {}
5 | ^^^^^^^^^^^^^^^^^^^ `X` cannot be made into an object
7 note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
8 --> $DIR/issue-67510-pass.rs:4:10
11 | - this trait cannot be made into an object...
13 | ^ ...because it contains the generic associated type `Y`
14 = help: consider moving `Y` to another trait
