# Test that we emit useful diagnostics when the same crate is loaded from the sysroot and --extern.
# This can't be a run-make test because it needs the aux-file to itself have a dependency passed with --extern
# (and just bare `--extern hashbrown` errors too early, while compiling `uses_hashbrown.rs`).
