// When setting the crate type as a "bin" (in app.rs),
// this could cause a bug where some symbols would not be
// emitted in the object files. This has been fixed, and
// this test checks that the correct symbols have been successfully
// emitted inside the object files.
// See https://github.com/rust-lang/rust/issues/51671
