--- Comment #2 from Dimitry Andric <dim@FreeBSD.org> ---
I can reproduce the error, and found that upstream's
https://reviews.llvm.org/rL212119 fixes it, however this is a commit that is
difficult to backport to clang 3.4.1 (it uses C++11 and is from quite a bit
post the upstream 3.5 version), not to mention that it is likely pretty risky.

As an "easy solution" I would recommend to make the port depend on, and use, a
newer version of clang, 3.8 or higher should do.  Might as well take clang 5.0
since that is used quite a lot in the ports tree already.
