Do we know if Clang is right or if it is a compiler bug?

Since it went into the codebase, I assume that the other compilers and other 
versions of Clang accepted it. I'm guessing it's a Clang update by Apple that 
caused it. Considering Clang 4.0 is currently unusable due to regressions, I'm 
not inclined to accept the failure as our fault.
