Note that the below error cannot be repeated by myself anymore...I tried minimizing the bug but then it disappeared and even after reverting back to the original troublesome code cargo no longer complains.

Code

use std::error::Error;
use hyper::{http::Method, Body, Request, Response};

async fn process(req: Request<Body>) -> Result<Response<Body>, Box<dyn Error + Send + Sync>> {
    let session = req
        .headers()
        .get("session")
        .map(|v| v.as_bytes())
        .unwrap_or(&[]);
    let dest = (req.method(), req.uri().path()).into();
    if authorized(session, &dest) {
        match dest {
            Dest::ECHO => {
                Ok(Response::new(req.into_body()))
            }
            Dest(_, _) => Ok(Response::new(Body::empty()))
        }
    } else {
        Err(format!("Unauthorized access to {dest:?}").into())
    }
}

pub(crate) fn authorized(_session: &[u8], dest: &Dest) -> bool {
    match *dest {
        Dest::ECHO | Dest::PLAYER_CREATE => return true,
        _ => {}
    }
    false
}

#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub(crate) struct Dest<'a>(&'a Method, &'a str);

impl<'a> From<(&'a Method, &'a str)> for Dest<'a> {
    fn from(tuple: (&'a Method, &'a str)) -> Self {
        Dest(tuple.0, tuple.1)
    }
}

impl<'a> Dest<'a> {
    pub const ECHO: Self = Dest(&Method::POST, "/echo");
    pub const PLAYER_CREATE: Self = Dest(&Method::POST, "/player/create");
}

FWIW, I have a case where this (at least it looks similar) happens all the time on stable and on nightly, including after cargo clean. Branch here: https://github.com/InstantDomain/instant-xml/tree/ice-2. To reproduce, just run cargo test. Running CARGO_INCREMENTAL=0 cargo test makes it work correctly.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.65.0-nightly (9243168 2022-08-31) running on aarch64-apple-darwin

note: compiler flags: -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C incremental

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
#0 [try_destructure_mir_constant] destructuring mir constant
#1 [check_match] match-checking <impl at instant-xml/tests/de-ns.rs:78:32: 78:39>::deserialize::<impl at instant-xml/tests/de-ns.rs:78:32: 78:39>::visit_struct
#2 [analysis] running analysis passes on this crate
end of query stack

cc @steffahn since you were able to triage the last one so quickly, maybe care to take a look?

@djc Your “All the compiler output” section is not formatted properly. Make sure to wrap things into a code block. It might necessary to leave an empty line between the ``` for the code fences and lines with HTML tags for <details>.

Regarding triage, I wouldn’t know how to tell whether or not the reproduction you have is actually “the same” issue as this one, so perhaps opening a new issue might be useful. I can reproduce it, and it’s nice (and interesting) that it’s appearing unconditionally, even though it looks similar to an incr-comp issue. Should make minimization easier though; if you open a new issue, make sure to tag it with E-needs-mcve :-) I don’t have time for minimizing myself today, but if no-one else picks it up, I might go for minimization within the next few days.

Let me quickly bisect your reproduction … apparently it is a regression from around May, so feel free to add regression-from-stable-to-stable to a new issue, too; I will edit in bisection results once it’s complete.

Edit1: The “May” figure might be inaccurate, just noticed that it might have simply not ICE’d before May because it fails with use of unstable library feature 'bool_to_option'

Edit2: Fixing the unstable features, this goes a lot further back; I haven’t even confirmed it’s a regression.

Edit3: Probably needs some minimization to simplify testing earlier Rust versions for whether there’s a regression, I can confirm this ICE goes back at least 2 years.
