  **Change:** New usual (non-placement) deallocator. **Rationale:**

  Required for sized deallocation. **Effect on original feature:** Valid
5
- C++11 code could declare a global placement allocation function and
6
  deallocation function as follows:

  ``` cpp

  void* operator new(std::size_t, std::size_t);

- In this International Standard, however, the declaration of
14
- `operator delete` might match a predefined usual (non-placement)
15
- `operator delete` [[basic.stc.dynamic]]. If so, the program is
16
- ill-formed, as it was for class member allocation functions and
17
- deallocation functions [[expr.new]].
