Neither one, since it's ambiguous, and the compiler
will tell you that. But so what? If you really want
to call one of them, you just say which one:
     int B::bar() { A2::foo(); }

If you need to disambiguate the two for further
inheritance, you rename and forward:

struct A1_r : public A1
{ virtual int foo_A1() { return A1::foo(); }
   int foo() { return foo_A1(); } };
struct A2_r : public A2
{ virtual int foo_A2() { return A2::foo(); }
   int foo() { return foo_A2(); } };

struct B : A1_r, A2_r
{
     int foo_A1(); // override A1's foo
     int foo_A2(); // override A2's foo
};
