            Bug ID: 45012
           Summary: clang accepts a call to an ambiguous inherited
                    constructor in some cases
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

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:

> If the constructor was inherited from multiple base class subobjects of type B, the program is ill-formed.
