tests/run-make/box-struct-no-segfault/rmake.rs

// The crate "foo" tied to this test executes a very specific function,
// which involves boxing an instance of the struct Foo. However,
// this once caused a segmentation fault in cargo release builds due to an LLVM
// incorrect assertion.
// This test checks that this bug does not resurface.
// See https://github.com/rust-lang/rust/issues/28766
