error[E0658]: casting pointers to integers in constants is unstable (see issue #51910)
--> $DIR/issue-52023-array-size-pointer-cast.rs:2:17
|
LL | let _ = [0; (&0 as *const i32) as usize];
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= help: add #![feature(const_raw_ptr_to_usize_cast)] to the crate attributes to enable
error[E0080]: it is undefined behavior to use this value
--> $DIR/issue-52023-array-size-pointer-cast.rs:2:17
|
LL | let _ = [0; (&0 as *const i32) as usize];
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^ type validation failed: encountered a pointer, but expected initialized plain (non-pointer) bytes
|
= note: The rules on what exactly is undefined behavior aren't clear, so this check might be overzealous. Please open an issue on the rust compiler repository if you believe it should not be considered undefined behavior
