 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)`.
 
-The **`/Zc:alignedNew`** option is only available when [`/std:c++17`](std-specify-language-standard-version.md) or later is enabled. Under **`/std:c++17`** or later, **`/Zc:alignedNew`** is enabled by default to conform to the C++ standard. If the only reason you implement operator **`new`** and **`delete`** is to support over-aligned allocations, you may no longer need this code in C++17 or later modes. To turn off this option and revert to the C++14 behavior of **`new`** and **`delete`** when you use **`/std::c++17`** or later, specify **`/Zc:alignedNew-`**. If you implement operator **`new`** and **`delete`** but you're not ready to implement the over-aligned operator **`new`** and **`delete`** overloads that have the `align_val_t` parameter, use the **`/Zc:alignedNew-`** option to prevent the compiler and Standard Library from generating calls to the over-aligned overloads. The [`/permissive-`](permissive-standards-conformance.md) option doesn't change the default setting of **`/Zc:alignedNew`**.
