// In a dependency hierarchy, metadata-only crates could cause an Internal
// Compiler Error (ICE) due to a compiler bug - not correctly fetching sources for
// metadata-only crates. This test is a minimal reproduction of a program that triggered
// this bug, and checks that no ICE occurs.
// See https://github.com/rust-lang/rust/issues/40535
