consider:
struct A {};
struct B : virtual A {};
struct __declspec(align(16)) C : virtual B {};
struct D : virtual B, A {};
struct E : virtual B, D, virtual C, A {};
struct F : virtual E, C, virtual A {};
struct G : virtual F, virtual C, virtual A {};
struct H : virtual B, virtual F, A {};
struct I : virtual C, A {};
struct J : virtual D, virtual I, virtual C, A {};
struct K : virtual D, virtual C, virtual A {};
#pragma pack(push, 2)
struct L : F,
           virtual I,  
           virtual B,
           virtual K,
           virtual E,
           virtual C,  
           D,
           virtual A {};
#pragma pack(pop)
struct M : virtual L,
           virtual G,
           virtual K,
           virtual J,
           virtual H,
           virtual I,
           C,
           virtual D,
           virtual B,
           virtual A {};
M x;

compile with:
clang++ -cc1 -cxx-abi microsoft -triple i386-pc-win32 different.cpp -fno-rtti
-emit-llvm -S -o -
