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

[Mehdi Amini via Release-testers]

Hi,

There has been a change in the libc++ header about  __call_once_proxy visibility, I suspect this is not a clean build?

Otherwise it means that your foo.o didn’t use the same libc++ headers as the one used to build libLLVMAnalysis.a.

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