warning: creating a shared reference to mutable static is discouraged
--> $DIR/static-recursive.rs:3:36
|
LL | static mut S: *const u8 = unsafe { &S as *const *const u8 as *const u8 };
| ^^ shared reference to mutable static

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