Rustc panics when running on a workspace about cargo-udeps HOT 6 CLOSED

I can run cargo-udeps on git checkouts of the quote and failure crates just fine, where failure depends on a proc macro crate that uses quote. I'm not sure how to reproduce it. I remember running into it myself but can't remember on which project.

A minimal reproducible example, or just any example, would be of great help.

Sure thing. Our workspace is pretty hairy, I'll try to pare it down and put something together today.

Likely this isn't due to cargo-udeps but a bug in save analysis creation.

I've recently added a backend not based on save analysis but on binary dep depinfo.

@sezna could you install latest cargo-udeps master (cargo install --locked --git https://github.com/est31/cargo-udeps) and run cargo udeps --backend depinfo? Does that work? Also cc @lovesegfault as he reported problems with current cargo-udeps as well.

I'll try and repro my issue again; it had happened as I attempted to move my company to a new nightly, and then we encountered an ICE in the cargo-udeps step of our CI.

I will attempt a bump again in the coming weeks, if I find the issue I'll report back with more details :)

I'll close this, as the save-analysis backend is in the process of removal. If an ICE occurs again, please write or open a new issue. Thanks!
