Description
Code
The compiler encounters an ICE while trying to document the aws-config crate. In particular, it seems to panic with a "no entry found for key" while collecting intra-doc links.
Steps to reproduce:
$ cd /tmp && cargo new repro && cd repro
Created binary (application) `repro` package
$ cargo add aws-config
Updating crates.io index
Adding aws-config v0.11.0 to dependencies.
Features:
+ rt-tokio
+ rustls
- native-tls
