warning: shared reference of mutable static is discouraged
--> $DIR/static-mut-xc.rs:28:18

LL | static_bound(&static_mut_xc::a);
| ^^^^^^^^^^^^^^^^^ 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
