# The ICE occurred in the following situation:
# * `foo` declares `extern crate bar, baz`, depends only on `bar` (forgetting `baz` in `Cargo.toml`)
# * `bar` declares and depends on `extern crate baz`
# * All crates built in metadata-only mode (`cargo check`)
all:
# cc https://github.com/rust-lang/rust/issues/40623
