            Bug ID: 30916
           Summary: If a class has indirect private virtual base with
                    non-trivial public destructor, a class cannot access
                    virtual base's destructor.
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

If a class has indirect private virtual base with non-trivial public
destructor, a class cannot access its virtual base's destructor.

Example code:

struct A
{
    ~A(){}
};

struct B: virtual private A
{
    ~B() {}
};

struct C: public B
{
    ~C() {}
};

Result:

prog.cc:11:8: error: inherited virtual base class 'A' has private destructor
struct C: public B
       ^
prog.cc:6:11: note: declared private here
struct B: virtual private A

GCC accept this code.
Clang until 3.3 accept this code.
Clang 3.4 and later reject this code.
