Comment (by RJVB):

 What do you mean with "the development git branch"? Do you mean that
 you're running some kind of beta OS or toolchain version?

 The failure:

 Yes, there appears to be the words "Syntax error" appended to the
 conftest.cpp file, using tabs for indentation. I have no idea where this
 can come from...

 Could you try with clang 5 or 6 from MacPorts (I have tested those myself,
 and I would avoid clang 8 because of a warning I saw somewhere)?
