[omniORB] sequence_var return passing

[Tom Kelly]

I have a problem sending a zero length sequence of octets through a return
type. Consider the following source as a testcase:

wib.idl:

typedef sequence<octet> octetSequence;

interface wib{
  octetSequence fib();
};

------

wib_i.cc:

#include "wib.hh"

class wib_i : public virtual _sk_wib{
public:
  wib_i(){}
  virtual ~wib_i(){}
  virtual octetSequence * fib(){
	octetSequence_var dummy(0); 
	return dummy._retn();}
};

------

If I now have on the client side:
octetSequence_var dummy(0);
wib_var objref = ... // get object reference somehow
dummy = objref->fib();

This causes the server to die with a segmentation fault. 
Collocating the client and server solves the problem. 
Am I allowed to pass back a zero length (is that the same as null)
sequence of octets? 

Thanks in advance,
Tom
