// On some platforms, -stdlib=libc++ is currently ignored, so -lc++experimental is not added.
// Once -stdlib=libc++ works on those, this XFAIL can be removed.
// XFAIL: target={{.*-windows-msvc.*}}, target={{.*-(ps4|ps5)}}

// For some reason, this fails with a core dump on AIX. This needs to be investigated.
