The problem is solved if I use macports-clang-3.4. But I still have no clue why the problem is there (with the default compiler) in the first place.

Here's some related discussion (different software, different function):

I would like to be able to create a minimal working example showing the problem with the compiler (to decide whether it's a compiler problem or something that could be easily fixed in ROOT sources), but I didn't manage to reproduce the problem outside of ROOT despite trying.

I would be grateful for some insight.
