    = 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.

This seems like a Miri-specific issue, so should probably be filed to that repo: https://github.com/rust-lang/miri/

Going to close this since the upstream issue was also closed.
