[omniORB] _CORBA_ObjRef_Element Self-assignment

[Felix Nawothnig]

Let's hope this I'm reporting a real bug this time. :-)

The assignment operator in _CORBA_ObjRef_Element don't check for
self-assignment - so I currently have a crash in the duplicate call() in

  inline T_element& operator= (const T_element& p) {
    if( pd_rel ) {
      T_Helper::release(pd_data);
      T_Helper::duplicate(p.pd_data);
      pd_data = p.pd_data;
    }
    else
      pd_data = p.pd_data;
    return *this;
  }

The _CORBA_ObjRef_Member::T_member& operator= (T_ptr p) implementation
looks suspicious too... I wouldn't expect that by assigning the actually
stored _ptr it now contains a freed (invalid) reference - but that might
actually be okay.

Cheers,

Felix
