warning: creating a mutable reference to mutable static is discouraged

--> $DIR/const_let_assign2.rs:18:24

LL | let ptr = unsafe { &mut BB };
|
|
| ^^^^^^^ mutable reference to mutable static
|
|
|
|
|
= note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2024/static-mut-references.html>
|
|
= note: mutable references to mutable statics are dangerous; it's undefined behavior if any other pointer to the static is used or if any other reference is created for the static while the mutable reference lives
|
|
= note: `#[warn(static_mut_refs)]` on by default
|
|
help: use `&raw mut` instead to create a raw pointer
