Looks like the failure is in an older version of cfg-if. If you update your Cargo.lock file, it should update to a version that skips this bug.

Minimal reproduction:

//! [cfg]

Looks like it's trying to treat [cfg] as an intra-doc-link link anchor, and found the #[cfg] attribute to match it to. We probably need to check whether the result of a lookup is a builtin attribute before trying to register it.

remram44 · 2019-06-15T23:44:05Z

Thanks, I'll try to update! This might be worth fixing in rustdoc though.

QuietMisdreavus · 2019-06-15T23:46:35Z

Yeah, i'm investigating how we'd fix this in rustdoc.

QuietMisdreavus · 2019-06-17T19:21:40Z

I've opened #61916 to start resolving intra-doc links to builtin macros.

orlp · 2019-07-14T16:11:27Z

I just reproduced this today on nightly with Windows 10. No issue on stable.

petrochenkov · 2019-07-20T18:47:21Z

Fixed in #62086.

Define built-in macros through libcore This PR defines built-in macros through libcore using a scheme similar to lang items (attribute `#[rustc_builtin_macro]`). All the macro properties (stability, visibility, etc.) are taken from the source code in libcore, with exception of the expander function transforming input tokens/AST into output tokens/AST, which is still provided by the compiler. The macros are made available to user code through the standard library prelude (`{core,std}::prelude::v1`), so they are still always in scope. As a result **built-in macros now have stable absolute addresses in the library**, like `core::prelude::v1::line!()`, this is an insta-stable change. Right now `prelude::v1` is the only publicly available absolute address for these macros, but eventually they can be moved into more appropriate locations with library team approval (e.g. `Clone` derive -> `core::clone::Clone`). Now when built-in macros have canonical definitions they can be imported or reexported without issues (rust-lang#61687). Other changes: - You can now define a derive macro with a name matching one of the built-in derives (rust-lang#52269). This was an artificial restriction that could be worked around with import renaming anyway. Known regressions: - Empty library crate with a crate-level `#![test]` attribute no longer compiles without `--test`. Previously it didn't compile *with* `--test` or with the bin crate type.
