It's using "DYLD interposing" to substitute its own functions in place of the malloc functions of libSystem. DYLD interposing of system APIs is pretty much impractical for anybody but Apple to use, since it is sensitive to exact symbol locations, which can change with any system update.
I see that interposing causes the creation of the special segment with
interposition pairs: one inner symbol and one imported one. It seems
like its quite self-contained.
Where are these Apple-dependent offsets that you are talking about?
