// Regression test for https://github.com/rust-lang/rust/issues/107407 which
// checks that rustc can read thin archive. Before the object crate added thin
// archive support rustc would add emit object files to the staticlib and after
// the object crate added thin archive support it would previously crash the
// compiler due to a missing special case for thin archive members.
