I tried this code:
#![feature(const_raw_ptr_to_usize_cast)]
#![feature(const_mut_refs)]
#![feature(raw_ref_macros)]
#![no_std]
static mut X: u32 = 0;
static P: usize = unsafe { core::ptr::raw_mut!(X) as usize };I expected to see this happen: The code either compiles successfully or fails to compile with a reasonable error message
Instead, this happened:
error[E0658]: `&raw mut` is not allowed in statics
--> src/lib.rs:8:28
|
8 | static P: usize = unsafe { core::ptr::raw_mut!(X) as usize };
| ^^^^^^^^^^^^^^^^^^^^^^

= note: see issue #57349 <https://github.com/rust-lang/rust/issues/57349> for more information
= help: add `#![feature(const_mut_refs)]` to the crate attributes to enable
= note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)
But the code already includes #![feature(const_mut_refs)].
