Code
mod inner {
/// [std::vec::Vec]
pub use std::vec::Vec as MyVec;
} Reproduces with just rustdoc repro.rs; no dependencies or Cargo needed.
Key conditions:
- A private module (
mod, not pub mod)
- A pub use re-export inside that module
- An intra-doc link (
[path::to::Type]) on the pub use item
The ICE doesn't tigger if any one of these three conditions is removed.
Meta
Reproduces on stable, 1.94, and nightly.
