[Release-testers] [4.0.0 Release] Release Candidate 1 source and binaries available

[Félix Cloutier via Release-testers]

Well, to be clear, there are 200ish occurrences of it from a clean build. I'm building with the libc++ version that ships with Xcode 8.2.1. With it, I could build my project against LLVM 3.9 without issues.

Should I be building with a different libc++?

This was likely caused by different translation units being compiled with different visibility settings.
