[INFO] [stdout]     = note: for more information, see issue #114447 <https://github.com/rust-lang/rust/issues/114447>
[INFO] [stdout]     = note: reference of mutable static is a hard error from 2024 edition
[INFO] [stdout]     = note: mutable statics can be written to by multiple threads: aliasing violations or data races will cause undefined behavior
[INFO] [stdout] 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
