“expected” and “found” interchanged in error message E0308

[gralpli]

I’m using rustc 1.33.0-nightly (a2b0f247b 2018-12-30).

trait MyTrait {
    type Item;
}

struct MyStruct<T> {
    item: T
}

impl<T> MyTrait for MyStruct<T> {
    type Item = T;
}

fn func<T: MyTrait<Item=i32>>(t: T) { }

fn main() {
    func(MyStruct { item: "str" });
}

func expects an MyTrait<Item=i32>, so the error message should say: “expected type i32, found type &str.” Instead, they’re interchanged and it says:

error[E0271]: type mismatch resolving `<MyStruct<&str> as MyTrait>::Item == i32`
  --> src/main.rs:17:5
   |
17 |     func(my_struct);
   |     ^^^^ expected &str, found i32
   |
   = note: expected type `&str`
              found type `i32`
note: required by `func`
  --> src/main.rs:13:1
   |
13 | fn func<T: MyTrait<Item=i32>>(t: T) { }
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Current output:

error[E0271]: type mismatch resolving `<MyStruct<&str> as MyTrait>::Item == i32`
  --> src/main.rs:16:5
   |
13 | fn func<T: MyTrait<Item=i32>>(t: T) { }
   |    ----            -------- required by this bound in `func`
...
16 |     func(MyStruct { item: "str" });
   |     ^^^^ expected &str, found i32
   |
   = note: expected type `&str`
              found type `i32`

Still same reversal.
