// A previously outdated version of LLVM caused compilation failures on Windows

// specifically with optimization level `z`. After the update to a more recent LLVM

// version, this test checks that compilation and execution both succeed.

// See https://github.com/rust-lang/rust/issues/45034

//@ ignore-cross-compile
