// A previously outdated version of LLVM caused compilation failures on Windows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

//@ ignore-cross-compile
// Reason: the compiled binary is executed
//@ only-windows
// Reason: the observed bug only occurs on Windows
