[github-actions]

Issue: rust-lang/rust#80767

type G<'a> = [(O, &'a [u8]); 64];
enum O {
    O1,
}
fn f(_p: [G; 4]) {}

fn main() {
    let p: [G; 4];
    let _g: G = [(O::O1, &[]); 64];
    f(p);
}

error[E0277]: the trait bound `(O, &[u8]): Copy` is not satisfied

9 |     let _g: G = [(O::O1, &[]); 64];
  |                 ^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `(O, &[u8])`

  = note: the `Copy` trait is required because the repeated element will be copied

error[E0381]: use of possibly-uninitialized variable: `p`

error: aborting due to 2 previous errors

Some errors have detailed explanations: E0277, E0381.
