<pre>Testcase:
struct A { A(int); };
struct B : virtual A { using A::A; };
struct C : A, B { using A::A; using B::B; };
C c(123);
Clang accepts and passes the 123 on to the constructors of both A base
subobjects. This code is ill-formed under [class.inhctor.init]p2:
<span class="quote">> If the constructor was inherited from multiple base class subobjects of type B, the program is ill-formed.</span ></pre>
