Well, I tested with Macports clang-3.8 - and the result is the same:

On a side-note, could you please explain how the version name/number of
this port changes? I recall seeing clang-3.7 @3.7-rXXXX, which then
changed to clang-3.7 @3.7.1_2. Now clang-3.8 is @3.8-r262722_1. At what
point would it become @3.8.1_x?
