As far as the FGPositioned Octree is concerned (which is what findClosest uses internally), it's holding an owning ref and hence things can't be removed from it, for the moment. So what I guess is happening, is that I'm breaking the ref-counting scheme *somehow*, and hence the Octree is left holding a dead reference as you say. And somehow how I get away with this on Mac. But this feels a little implausible, since in other similar scenarios the Mac crashes quite happily!
