trim-paths = "all" causes rustdoc ICE

[crumblingstatue]

Create a new crate with trim-paths enabled in dev profile, and a dependency to document

cargo-features = ["trim-paths"]

[package]
name = "mycrate"
version = "0.1.0"
edition = "2024"

[dependencies]
rand = "0.9.0"

[profile.dev]
trim-paths = "all"

Then run cargo doc:
