ICE when documenting crate that triggers PR 31362 warning

[Moredread]

I get an ICE on an older project, when running cargo doc - when documenting glium v0.13.5 specifically - with the current nightly build.

The issue seems to be the line in src/lib.rs of that glium version

pub use backend::glutin_backend::glutin;

The glium crate is linked in the backend::glutin_backend module. The compiler warns about PR #31362, but at the moment it compiles fine, only generating docs doesn't work.

A minimal example, that generates the same behaviour, when documenting, is:

lib.rs:

pub use bar::std;
pub mod bar {
    extern crate std;
}

cc @jseyfried, looks like this points to #35776, any ideas here?

[jseyfried]

Hmm, that's odd -- I'll investigate.

[jseyfried]

Fixed in #37023.
