It's a warning. A programming paradigm used in older versions of OS X fell from favor in version 10.7. We still maintain a Snow Leopard (i.e. OS X 10.6) build. The question is whether the intended paradigm replacement actually works in 10.6; otherwise, it could be undesirable to maintain two different codes for the two different builds.

I don't see the warning as related to any segfault? Being able to continue work following a segfault would be quite unusual so I suspect that you're using the term incorrectly.

If you want to contribute, you might dig into the source code for R.app and figure out what it is that needs to be replaced and by what. And then whether the "what" is present in the Snow Leopard toolchain. The closest I can get is stuff like this:

Mind you, Simon might already know all about this and just needs to get around to sorting things out.
