Rustc v1.70 nightly panics unexpectedly

[preston-evans98]

I tried this code: I was in the process of developing a somewhat complicated macro to derive clap::Parser on a generic type, and I encountered an unexpected panic in Rustc. The full code to reproduce the panic is here: https://github.com/Sovereign-Labs/sovereign-sdk/pull/423/commits/5935c6727e6f347f5f42fb4463e7595971799e01. To reproduce...

1. git clone https://github.com/Sovereign-Labs/sovereign-sdk.git && cd sovereign-sdk
2. git checkout 5935c6727e6f347f5f42fb4463e7595971799e01
3. cargo check

I expected to see this happen: explanation

The code in question is almost certainly not correct, but it should have produced an error rather than a panic.

Instead, this happened: explanation

A bit hard to bisect this one, considering there's no Cargo.lock and most of the dependencies end up being resolved to a version too new for the compiler to handle (not to mention reproducibility). As an additional bonus, the specified commit cannot even be found in the repository (thankfully, it is still possible to just download it as an archive instead of cloning it).
