Testcase:
struct B1 { void f(); };
struct B2 { void f(double); };
struct I1 : B1 { };
struct I2 : B1 { };
struct D: I1, I2, B2 {
using B1::f; using B2::f;
void g() {
f();
}
};
gcc-4.6:
clang-7.C:10:7: error: B1 is an ambiguous base of D
clang:
t.cc:10:5: error: ambiguous conversion from derived class 'D' to base class
'B1':
struct D -> struct I1 -> struct B1
struct D -> struct I2 -> struct B1
f();
^
Clang prints the hierarchy, which is something that g++ doesn't support (I
think).
