There are no different ORB objects. The ORB object is a singleton and 
you can have only one per process. (You should be able to have multiple 
references to the ORB via many ORB_var reference objects though)

What calls? Calls on the ORB object (eg to resolve a naming service) or 
calls on some other objects in the servers?

Specify "crash". If it's reproducible attach a debugger and check what 
happens.
