Hi Robin, thanks for the extra info. I have no clue what the problem might be.
But from R-level debugging (and the R traceback you wrote originally), I assume you could trigger the problem already by a simple median(rep(1000, 10)) is that the case? If yes, please follow up on R-devel. In any case, let's wait for others (Mac specialists and/or other R-core members) to voice ideas.
