Ah, you meant run time problems, sounds more reasonable, now that I think
about it....., but you don't want a version check in every call to a
stub/skel? I actually don't see a simple solution to that problem. However I
think we can savely ignore that special issue someone's using an externel
compiled ORBit program locally with an ancient ORBit library.

Its up to you. Enabling that error return sounds like a good solution though. 

While I think about it another possibility would be to check in
giop_recv_reply_buffer_use_2, that the connection cnx is still alive and
return otherwise. That would be simple and portable and would solve this very
problem as well, I suppose.

Bye,
Sebastian
