| LL | let ptr = unsafe { &mut BB }; |
| | ^^^^^^^ mutable reference to mutable static |

| = note: for more information, see issue #114447 <https://github.com/rust-lang/rust/issues/114447> |
| = note: this will be a hard error in the 2024 edition |
| = note: this mutable reference has lifetime `'static`, but if the static gets accessed (read or written) by any other means, or any other reference is created, then any further use of this mutable reference is Undefined Behavior |
| = note: `#[warn(static_mut_refs)]` on by default |
| help: use `addr_of_mut!` instead to create a raw pointer |
