| error[E0277]: the trait bound `X: Ord` is not satisfied | |
| --> $DIR/issue-20162.rs:5:7 | |

| LL | b.sort(); | |
| | ^^^^ the trait `Ord` is not implemented for `X` | |
| | | |
| note: required by a bound in `slice::<impl [T]>::sort` | |
| --> $SRC_DIR/alloc/src/slice.rs:LL:COL | |
| help: consider annotating `X` with `#[derive(Ord)]` | |
| | | |
| LL + #[derive(Ord)] | |
