Follow-up Comment #3, patch #9294 (project lwip):

Really? Let me rephrase your test:
p = p + 72;
p1 = p + 72;
ASSERT(p1 == p);

That can't work (the 2nd line works on a changed 'p'). I don't think the added
size_t cast fixes anything. I assume you do have memp overflows but I don't
understand why you think it is fixed after adding the extra cast.
