Huh, it hasn't made it to my mirror yet.
Anyway, I upgraded and built with LLVM 6 and make check now passes on
my arm64 system. Woohoo!
Via an off-list exchange I learned that Andres suspects a bug in LLVM
3.9 on arm64 and will investigate/maybe file a bug report with LLVM.
Not sure if we'll want to try to actively identify and avoid known
buggy versions or not?
