--- Comment #5 from Dimitry Andric <dim at FreeBSD.org> ---
Some bisection shows that this has been fixed by upstream llvm commit r219512
[1], as a fix for LLVM PR 18883.  It looks like this fix applies without fuzz
on clang 3.4, and probably also on clang 3.5.

I'm currently building stable/9 world with it, to see if it causes any
problems, but I don't really expect them.  If it works, I will merge it to
stable/9.

Brooks, we should probably add this fix to both the llvm34 and llvm35 ports.
