Thank you Josh. Unfortunately that doesn’t help as the same compilers are selected on OSX 10.8-10.10 and, therefore, the build still fails. It seems to me that base thinks that Clang 5 and above do support this () .So it makes sense that these compilers are used but it doesn’t seem to work. For now I think I’ll just switch the option off for older OS X versions or try to blacklist Clang < 7 and see it that helps.
