brew uninstall protobuf
brew install homebrew/versions/protobuf260 --c++11
You still need to use Protobuf 2.6, the OS X build docs were only recently updated.
It didn't look like a protobuf incompatibility issue to me but something with atomics / endian swapping compat. But I think you're right, it looks like it happens in the qt files that also include protobuf.
Issue for protobuf 3.x support is #8430.
