The MSVC compiler and library support C++17 standard over-aligned dynamic memory allocation. When the **`/Zc:alignedNew`** option is specified, a dynamic allocation such as `new Example;` respects the alignment of `Example` even when it's greater than `max_align_t`, the largest alignment required for any fundamental type. When the alignment of the allocated type is no more than the alignment guaranteed by the original operator **`new`**, available as the value of the predefined macro `__STDCPP_DEFAULT_NEW_ALIGNMENT__`, the statement `new Example;` results in a call to `::operator new(size_t)` as it did in C++14. When the alignment is greater than `__STDCPP_DEFAULT_NEW_ALIGNMENT__`, the implementation instead obtains the memory by using `::operator new(size_t, align_val_t)`. Similarly, deletion of over-aligned types invokes `::operator delete(void*, align_val_t)` or the sized delete signature `::operator delete(void*, size_t, align_val_t)`.
