Compiler Error C2292

'identifier': best case inheritance representation: 'representation1' declared but 'representation2' required

Example

Compiling the following code with /vmb ("Best-case always" representation) causes C2292.

// C2292.cpp
// compile with: /vmb
class __single_inheritance X;

struct A { };
struct B { };
struct X : A, B { };  // C2292, X uses multiple inheritance
