'new TYPE[0]' returns a ptr to the start of an array of zero TYPE
-which is zero in front of one past the end of the array.

sizeof(TYPE[0]) == 0 * sizeof(TYPE) == 0
for the theoretical size of the allocation.

"new TYPE[0]" would consume at least four bytes in practice. And if
the implementation uses an additional four-byte word to record the
allocation size, 'new TYPE[0]' consumes a total of eight bytes -for
nothing!
