rustdoc ICE: no resolutions for a doc link

[kyp44]

Code

Panic occurs when running cargo doc on my project here. This is specifically on the current transfer branch of the project with commit hash c1d04db7977d2de43d69ea9f8795905f60b3b8ba. Note that this project does include the Cargo.lock file, and that the project compiles normally (i.e. with cargo build) just fine.

Error output

There are numerous panics when running cargo doc, but the first one seems to happen while Checking serde_json v1.0.94:

This may have been fixed by #109266. Does it work on the most recent nightly?

[smmoosavi]

it was ok in rustc 1.70.0-nightly (da7c50c08 2023-03-19) but have error in 1.70.0-nightly (44f518058 2023-03-20)

whose repro is creating a dependency on rustix = "=0.36.10" followed by cargo +nightly doc, using nightly 1.70.0-nightly (a266f1199 2023-03-22) on x86_64-unknown-linux-gnu. (rustix 0.37 does not trigger it; nor does building on macOS instead of Linux.)

https://github.com/bytecodealliance/rustix/blob/5caa325f24cbb421c54fb4416c21888865a0c3b1/src/io/read_write.rs#L14 is the line which the ICE occurs on. bytecodealliance/rustix#539 removed this line which is why the ICE goes away
