If the example is something like:

       // C++ 
       CORBA::TypeCode_var new_tc = orb->create_struct_tc(
                     "IDL:MyStruct:1.0",
                     "MyStruct",
                     mems
       );

Then the return type *is* CORBA::TypeCode_ptr, it's just that the
client is using an _var type to wrap it so that they don't have to
call CORBA::release() on the reference after use.

Probably because the reference is being prematurely released by a
temporary _var. (Any C++ lawyers care to confirm or deny?)
