PR introducing this ICE: #92364
cc @jackh726

Line producing this ICE:

rust/compiler/rustc_typeck/src/check/fn_ctxt/checks.rs

Lines 430 to 432 in b6c87c5

let Error::Invalid(input_idx, Compatibility::Incompatible(error)) = error else { return false };
let expected_ty = expected_input_tys[*input_idx];
let provided_ty = final_arg_types[*input_idx].map(|ty| ty.0).unwrap();

My attempt at an explanation: #92364 (comment)

First discovered by Clippy's integration tests: https://github.com/rust-lang/rust-clippy/runs/6212887812?check_suite_focus=true#step:7:22

Can also be reproduced by running cargo +nightly-2022-05-01 check --all-targets --all-features on chalk.

Code

fn f(_: usize, _: &usize, _: usize) {}

fn arg<T>() -> T { todo!() }

fn main() {
    let x = arg(); // `x` must be inferred
    f(&x, ""); // The reference on `&x` is important to reproduce the ICE
}

Info: Does this ICE only occur in the error path?

Not sure what's going on exactly. The index should only be less than than the provided args length:

rust/compiler/rustc_typeck/src/check/fn_ctxt/arg_matrix.rs

Line 145 in 5428983

(true, true, true, true) => return Some(Issue::Invalid(i)),

I think the code in arg_matrix is wrong. I think we're missing a "mapping" back to the original provided and expected arg indices. I think instead of just passing i into Issues here, we should be doing ai[i] and/or ii[i].

Kind of interesting this didn't break before this. The arg_matrix code would be a good candidate for a fuzzer, I think.

Interestingly enough, the resulting output if changing a few indexing operations with .get(idx) is quite sane:

I'll put up a PR to address the immediate ICE, but we can leave this ticket closed for further inspection of the logic.

When fixing the underlying issue, the logic changes from #96646 should be reverted, while keeping the regression test.

Mitigate impact of subtle invalid call suggestion logic

There's some subtle interaction between inferred expressions being
passed as an argument to fn calls with fewer than expected arguments. To
avoid the ICE, I'm changing indexing operations with `.get(idx)`, but
the underlying logic still needs to be audited as it was written with
the assumption that `final_arg_types` and `provided_args` have the right
length.

Address rust-lang#96638.
