This was OSX 10.12.5 (Sierra) running Apple LLVM version 7.0.0 (clang-700.1.76) (running strings on the binary suggests this is based on upstream clang 3.7.0) and Linux Ubuntu x86_64 Xenial running clang version 3.8.0-2ubuntu4 (tags/RELEASE_380/final) and FreeBSD 11.0 running FreeBSD clang version 3.8.0 (tags/RELEASE_380/final 262564) (based on LLVM 3.8.0) If we don't build with clang 3.9 that's worth fixing; it's not in my test set, which will be why the breakage has slipped through. thanks -- PMM
