warning: shared reference of 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 of mutable static
|
|
|
|
|
= note: for more information, see issue #114447 <https://github.com/rust-lang/rust/issues/114447>
|
|
= note: reference of mutable static is a hard error from 2024 edition
|
|
= note: mutable statics can be written to by multiple threads: aliasing violations or data races will cause undefined behavior
|
|
= note: `#[warn(static_mut_ref)]` on by default
|
|
help: shared references are dangerous since if there's any kind of mutation of that static while the reference lives, that's UB; use `addr_of!` instead to create a raw pointer
