warning: integer-to-pointer cast

--> $DIR/issue-miri-2389.rs:LL:CC

LL | let wildcard = &root0 as *const Cell<i32> as usize as *const Cell<i32>;

|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ integer-to-pointer cast
|
|
|
|
|
= help: This program is using integer-to-pointer casts or (equivalently) `ptr::from_exposed_addr`,
|
|
= help: which means that Miri might miss pointer bugs in this program.
|
|
= help: See https://doc.rust-lang.org/nightly/std/ptr/fn.from_exposed_addr.html for more details on that operation.
|
|
= help: To ensure that Miri does not miss bugs in your program, use Strict Provenance APIs (https://doc.rust-lang.org/nightly/std/ptr/index.html#strict-provenance, https://crates.io/crates/sptr) instead.
|
|
= help: You can then pass the `-Zmiri-strict-provenance` flag to Miri, to ensure you are not relying on `from_exposed_addr` semantics.
|
|
= help: Alternatively, the `-Zmiri-permissive-provenance` flag disables this warning.
