ICE on cargo doc with dependency [email protected] in current nightly

[chipnertkj]

Please inform me if there is anything else I can do to help.
rustc-ice-2024-11-14T02_19_01-19724.txt

Reproduce

I don't have another environment to test this in, but in my case, the steps appear to be:

1. Create a new crate, doesn't matter if it's a library.
2. Add [email protected] to dependencies.
3. Attempt to run cargo doc.

Thanks for the report! This is a duplicate of #132743, so closing in favor of that.

Ah, I missed it, my bad! Glad it's being worked on 😊
