Message: [QUOTE="Keith Thompson, post: 4037641"] I'm skeptical that that would even be possible in most implementations. On the implementations I've seen, size_t is big enough to span the machine's entire addressing space; an object bigger than 2**SIZE_MAX bytes isn't even possible. The only plausible scenario I can think of is an implementation that deliberately restricts the size of an object for some reason. If some external magic provides the address of a huge object, it's not clear that a program could even index it (an attempt to do so presumably would invoke undefined behavior). I suspect we're in DS9K territory. [/QUOTE]
