Description
It's hard for me to provide a MRE, since I can't reproduce the error locally or on GitHub pipelines.
The compilation of docs of my crate fails on docs.rs with an internal compiler error when compiling the time crate (v0.3.9).
I've created an issue at docs.rs repo and asked for a rebuild, but it failed with the same error.
My docs pipeline succeeds on newest nightly, it also works when I run docs locally on Ubuntu 22 (x86_64-unknown-linux-gnu).
Error output
See the two builds on docs.rs: https://docs.rs/crate/rsonpath/0.1.0/builds/593904, https://docs.rs/crate/rsonpath/0.1.0/builds/593800
