Just an FYI... Clang 3.7 and below do not witness the problem. Clang 3.8 and
above do.

If you are working on OS X and want to avoid iTunes accounts and the App Store,
then you can duplicate with MacPorts:

   # port install clang-3.8
   # port install gcc6
   # ln -s /opt/local/bin/clang /opt/local/bin/clang-3.8

(My apologies if I got the link backwards; I always do it in real life, too).

Then:

   CC=/opt/local/bin/gcc-mp-6 CFLAGS="-Wa,-q" make

Creating the link and using the full path allows you to keep MacPorts off-path.
I keep it off-path to avoid cross-pollination in a testing environment.
