After two failed attempts last week to make this work I am going back to a known good method of making this test pass on macOS...adding the current apple-clang version to the UNSUPPORTED list. During a previous patch review (https://reviews.llvm.org/D44103) it was suggested to just XFAIL libcpp-no-deduction-guides as was done to iter_alloc_deduction.pass.cpp. However this caused a an unexpected pass on: http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-gcc-tot-latest-std/builds/214 I then attempted to just mark libcpp-no-deduction-guides as UNSUPPORTED, however this caused an additional bot failure. So I reverted everything (https://reviews.llvm.org/rCXX327191). To solve this and get work unblocked I am adding apple-clang-9 to the original UNSUPPORTED list. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@327304 91177308-0d34-0410-b5e6-96231b3b80d8
