callback problem

[robsta stereolyzer net]

Hello, 

i've not been able to find a corba callback sample written in c. So i
started poking around myself based on orbit's mt-calculator sample.

To be able to receive callbacks on the client side i copied the
server code and activated my listener object which i then pass on to
the server. 

Now i'm cleaning up the code a bit and would like to have only one
initialisation - previously i had client init AND server init funcs
on the client. The problem is since i removed the client's
CORBA_ORB_init(single threaded) it's not working any more. There's
two variants of failure as explained below.

Maybe anyone even got a piece of code which is running multithreaded
CORBA server and client functionality in one process at hand?

Thanks, 
Rob
