My GCC is 4.9.2, and I can't reproduce your error. But where GCC is
4.8, I can. I'm not sure why is that, since we're using Clang, but it
deserves some investigation.

Basically, the error message is saying that "d16" is not a valid
register name. If you change to -mfpu=vfpv3 everything works, so it's
definitely a run time issue.
