=== stdout ===
=== stderr ===
error[E0277]: the trait bound `(O, &[u8]): Copy` is not satisfied
 --> /home/runner/work/glacier/glacier/ices/80767.rs:9:17
  |
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`
  --> /home/runner/work/glacier/glacier/ices/80767.rs:10:7
   |
10 |     f(p);
   |       ^ use of possibly-uninitialized `p`

error: aborting due to 2 previous errors
