The -prune action needs stat information when -depth is not given, but find's
parser fails to declare this. It is therefore possible for -prune to use
undefined stat data.

I've attached a patch (against the rel-4-4-fixes branch, I'm afraid; I have
spent the whole afternoon trying to track this down in the face of half our
developers complaining because all their builds are breaking, so I'd rather do
something else right now, but I wanted to get this patch sent; if you need it
reconstructed against master then I can do that tomorrow), including a test
that you may be able to get to demonstrate the problem. Whether the test
actually fails for you is unfortunately not certain, since it's an
undefined-data problem; you should at least be able to see the bug manually by
breaking on pred_prune.
