Code

For now I only have a branch, which can be found at https://github.com/InstantDomain/instant-xml/tree/ice-2. To reproduce, run cargo test with either stable (currently 1.63.0) or nightly. Using CARGO_INCREMENTAL=0 makes the problem go away. cargo clean doesn't help.

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 1.63.0 (4b91a6ea7 2022-08-08) 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`
#2 [analysis] running analysis passes on this crate
end of query stack

#97858 had a similar error but seems to have been intermittent, while this reproduces every time.

Minimized:

#[derive(PartialEq, Eq)]
struct Id<'a> {
    ns: &'a str,
}
fn visit_struct() {
    let id = Id { ns: "random1" };
    const FLAG: Id<'static> = Id {
        ns: "needs_to_be_the_same",
    };
    match id {
        FLAG => {}
        _ => {}
    }
}
fn visit_struct2() {
    let id = Id { ns: "random2" };
    const FLAG: Id<'static> = Id {

    };
    match id {
        FLAG => {}
        _ => {}
    }
}

godbolt shows it ICEs as far back as 1.42.0 from 03/2020.

Thanks for the MCVE. I suspect an issue with AllocId, like most issues that feature the same exact ICE. Working on a refactor to get this unstability out of the way.

Ah, damn, I just minimized it, too xD

Looks roughly the same.

Note that it only ICEs with incremental compilation turned on (hence e.g. it doesnt reproduce on the playground.

Add a few known-bug tests

The labels of these tests should be changed from `S-bug-has-mcve` to `S-bug-has-test` once this is merged.

I couldn't reproduce the failures in rust-lang#101962 and rust-lang#100772 (so either these have started passing, or I didn't repro properly), so leaving those out for now.

rust-lang#102065 was a bit more complicated, since it uses `rustc_private` and I didn't want to mess with that.
