[Bug c++/19351] operator new[] can return heap blocks which are too small

Why is this undefined behavior?  Would you quote chapter and verse, please?

GCC's behavior violates 5.3.4(10):

"A new-expression passes the amount of space requested to the allocation
function as the first argument of type std::size_t.  That argument shall be no
less than the size of the object being created; [...]"

In this case, the passed value is 16, which is much smaller than the size of the
array.
