Uses the outer allocator to allocate uninitialized storage.
1) Calls std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n).
2) Additionally provides memory locality hint, by calling std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n, hint).
Parameters
| n | - | the number of objects to allocate storage for |
| hint | - | pointer to a nearby memory location |
Return value
The pointer to the allocated storage.
