            Bug ID: 28885
           Summary: Regression concerning inheriting constructor
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: abramo.bagnara at bugseng.com

    Classification: Unclassified

The following typescript shows that AST for UsingDecl constructor name has been
recently changed in a wrong way. It is possible it is related to recent changes
in inheriting constructors implementation.

$ cat p.cc
struct A {
    A();
};

struct B : A {
  using A::A;
};

$ clang++-3.8 -cc1 -ast-print -std=c++11 p.cc
struct A {
    A();
};
struct B : A {
    using A::A;
};
$ clang++-3.9 -cc1 -ast-print -std=c++11 p.cc
struct A {
    A();
};
struct B : A {
    using A::B;
};
