Hi Victor,
thanks a lot for your patch. It's correct and solving your issue, but
I'm afraid here you hit different bug in MICO than what you thought.
First of all, I'd like to let you know that following CORBA spec, at
least as I read it (strickly) is that the construct you are using in
myidl2.idl is not legal. Following IDL grammar you can use just
<interface_name> on this place, where <interface_name> is <scope_name>
-- but not any kind of alias. So as MICO was always focused on
correctness of CORBA implementation I'm not going to merge your attached
patch. What I would certainly consider for merging is a patch which will
fix the crash in your case and emit some clear error message complaining
about not valid IDL.
Thanks!
Karel
