ICE when documenting embedded-io with nightly: `node HirId(...) cannot be placed in TypeckResults`

[robamu]

I receive an ICE trying to build the nightly docs for the embedded-io library.

Reproduction Steps

git clone https://github.com/rust-embedded/embedded-hal.git
cd embedded-hal/embedded-io
RUSTDOCFLAGS="--cfg docsrs --generate-link-to-definition -Z unstable-options" cargo +nightly doc

Expected Outcome

Docs build.

Actual Output

❯ RUSTDOCFLAGS="--cfg docsrs --generate-link-to-definition -Z unstable-options" cargo +nightly doc
 Documenting embedded-io v0.7.1 (/home/muellerr/Rust/embedded-hal/embedded-io)
