The problem doesn't exist on OS X 10.6 though, so it could be Apple broke it for 10.7 or it could be compiler related.

fwiw I've compiled 0.10.0 both on 10.7 and 10.5/ppc, 9 test failures just like on 10.6/x86_64 but 
defintitely no segfaults or the like - so this rather seems to be a compiler issue.
