I believe this is the same failure I'm seeing on nightly: https://github.com/aws/aws-lc-rs/actions/runs/9225266351/job/25382407173?pr=410#step:5:127

error: 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: please make sure that you have updated to the latest nightly

note: please attach the file at `/home/runner/work/aws-lc-rs/aws-lc-rs/rustc-ice-2024-05-24T14_08_10-3884.txt` to your bug report

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -Z sanitizer=address

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

query stack during panic:
end of query stack
error: could not compile `aws-lc-rs` (lib test)

This occurred in our CI, but I can attempt to reproduce locally to provide more details if needed.

I have a local fix but haven't yet managed to make a unit test out of the repros, making hard to ensure it won't regress.

I think I'm getting this too, if it's different I can make a new issue

Care to explain why it happens?

In my case, having a re-export with different version than the one in Cargo.toml.
Specifically egui and eframe, but I don't believe it's anything to do with them, or the specific struct.

use eframe::egui;

fn main() {
    egui::Key::A;
}

this is the Cargo.toml:

[package]
name = "ice"
version = "0.1.0"
edition = "2021"

[dependencies]
eframe = "0.27"
egui = "0.26"

This is a regression that I think does not yet show up on beta (IIUC). In two weeks it will.

Let's keep in mind the fix from @lqd in #125493 (thanks!)

Nightly rust tests are failing, seemingly due to
[rust-lang/rust#125474](rust-lang/rust#125474).

This PR fixes the toolchain to the last working nightly until the
problem is resolved.

Revert "use `tcx.used_crates(())` more" before it reaches beta

There are more open issues caused by rust-lang#124976 than will be fixed by rust-lang#125493 alone. The beta cut is soon, so let's revert it and buy some time to analyze and fix these issues in our own time.
