In fact, we used to only call clobber k.j. Because our standards experts tell us that doing pointer arithmetic magic to get back to k.i is legal, we could only consider this function to clobber *just* k.j if the pointer doesn't escape from f, *and* f does not do any pointer arithmetic on it's arguments. This is usually *not* the case, making this testcase more or less "not interesting at all".
