[omniORB] bug: duplication of a nil reference

[Shawn Bisgrove]

Hello,

  I am under the impression that one should be able to

duplicate a nil reference.  If this is wrong let me
know.  This problem would arise in the copying of a
struct containing a nil reference to an object.

   Build: 4/17/00 OmniOrb 3
   Platform: Solaris 2.6 (GNU Compiler 2.95.2)
   Problem: cannot duplicate a nil reference.

= problem.idl ========================================

module TEST
{
        interface Product { };

        struct ProductStructure
        {
                Product pInterface;
        };
};

= test.cc ============================================
#include "problem.hh"

void main ()
{

   TEST::ProductStructure ps;
   ps.pInterface = TEST::Product::_nil();
   TEST::ProductStructure other;
   ps = other;   // error occurs here
}

======================================================
