Compiler Error C2798

'super::member' is ambiguous

Multiple inherited structures contain the member you referenced with super. You could fix the error by either:

  • Removing B1 or B2 from the inheritance list of D.

  • Changing the name of the data member in B1 or B2.

The following sample generates C2798:

// C2798.cpp
struct B1 {
   int i;

struct B2 {
   int i;

struct D : B1, B2 {
   void g() {
      __super::i = 4; // C2798
