Hi all,

I wonder what is the result of allocating an array of zero objects?
A NULL-pointer? Or undefined/unpredictable?

Thanks, Tom

>From section 5.3.4 "New":

"When the value of the expression in a direct-new-declarator is
zero, the allocation function is called to allocate an array with
no elements. The pointer returned by the new=ADexpression is non=ADnull.=20
[Note: If the library allocation function is called, the pointer
returned is distinct from the pointer to any other object. ]"

So you will get a non-null pointer, but you cannot dereference
it, since it doesn't point to an object.
