// test get_new_handler

// FIXME: When libc++ is linked against vcruntime (i.e. the default config in
// MSVC mode), the declarations of std::set_new_handler and std::get_new_handler
// are provided by vcruntime/UCRT's new.h. However, that header actually only
// declares set_new_handler - it's missing a declaration of get_new_handler.

// XFAIL: msvc
