           Summary: Error on throwing pointer to pointee with non public
                    destructor
           Product: clang
           Version: 2.8
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

When throwing a pointer, clang wants the dtor of the pointee to be public.

class Error {
  virtual ~Error() {}
public:
  // uses decref() and incref() for reference counting
};

void throwing() {
  throw new Error;
}

int main(int argc, char *argv[])
{
  try { throwing(); }
  catch (Error* e) { }
  return 0;
}

// clang++ -o test test.cpp 
// test.cpp:8:9: error: exception object of type 'Error' has private destructor
//   throw new Error;
//         ^
// test.cpp:2:11: note: declared private here
//   virtual ~Error() {}
//           ^
// 1 error generated.
