[omniORB] Re: DynAny & CORBA 2.3 spec.

[Francois Laflamme]

Thanks for your help David,

We`ve try the following code with the orb v.2.8 and we get an assertion
failure from debug heap pointer (under vc++ v6) when the Any_var goes out of
scope.
//////////////////////////
{
	CORBA::DynAny_var da;
	CORBA::Any_var a;

	da = Orb->create_basic_dyn_any(CORBA::_tc_long);
	da->insert_long(1);

	a = da->to_any();


	da->destroy();
}
//////////////////////////

Should we absolutly use the v.3 to make it running?

Thanks again!

Olivier & Frangois
