I don't know, but the obvious(?) question I have is, "why?"
I was hoping nobdy would ask ;) Because we need to override malloc, and the only way we can figure out to do it is to - force a flat namespace using DYLD_FORCE_FLAT_NAMESPACE - link applications with -multiply_defined -u foo_hack() - add foo_hack() into scalable_malloc.c along with the hooks we need - include the scalable_malloc.o object in our lib. As I understand it (I didn't come up with it) this forces the rtld to load our scalable_malloc.o rather than the one from libc, since the first thing it does is to go looking for foo_hack().
