            Bug ID: 40354
           Summary: libc++ tests fail with "aligned allocation function of
                    type 'void *(std::size_t, std::align_val_t)' is only
                    available on macOS 10.14 or newer"
           Product: libc++
           Version: 8.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: hans at chromium.org
                CC: llvm-bugs at lists.llvm.org, mclow.lists at gmail.com

I assume this is due to https://reviews.llvm.org/D56445

This came up while testing the new 8.0 branch on mac. Please see the example
failure below. The full build log is attached.
