Compiler Warning (level 3) C4359

'type': actual alignment (8) is greater than the value specified in __declspec(align())

The alignment specified for a type is less than the alignment of the type of one of its data members. For more information, see align.

Example

The following sample generates C4359.

// C4359.cpp
// compile with: /W3 /c
struct __declspec(align(8)) C8 { __int64 i; };
struct __declspec(align(4)) C4  { C8 m8; };   // C4359
struct __declspec(align(8)) C8_b  { C8 m8; };   // OK
struct __declspec(align(16)) C16  { C8 m8; };   // OK
