Hi everybody.
I am trying to use some of the dynamic features of corba, nammely I
trying to discover
the interface description and signatures of an object at runtime. In
orderto do this I
call _get_interface(), but the server program crashes.
Bot the name server and the interface repository are running and are
konwn to omniORB by means
of the default configuration file. The interface repository is that of
mico.
Client and server are compiled whit omniORB-4.0.1 on hpux-11.00. Clien
and server are compiled
with ENABLE_CLIENT_IR_SUPPORT tunrd on.
Some preliminary tests show that the _get_interface() problem is present
under linux also.
In the attechment document you will find the debugger stack trace of the
server and its output
with traceLevel=40.
Apart from the missing "introspection" capabilty, it is very dangeorous
that a legal call can crash your server!
Greetings.
