The C++ compiler does not support this extension to the C++ standard as described in The Annotated C++ Reference Manual (Addison-Wesley) by Ellis and Stroustrup:

• Overloading methods operator new[] and operator delete[] to allocate and deallocate the memory for a whole array of objects at once. Instead overload operator new() and operator delete(), which are the functions that operator new[] and operator delete[] call (ARM, §5.3.3, §5.3.4).
