Hey all !
Here is a nice issue I have with Ada (GNAT 2012) when trying to do OO 
dispatching with streams in different tasks ...

Here it is :
I'd like to get from a task RdV (Entry-Access) an object which could be 
any subclass of a root'Class, and pass it to another task

Context : read (Root'Class'Input() ) tagged records from an input 
stream, and send them to anther task which will write 
(Root'Class'Output() ) the given records to another output stream.

I'm stuck with task memory isolation with does NOT allow to pass any 
access object to a Root'Class.

Should I try to use a protected object ?
(not shore this solves the passing of a Class-wide object ...)

Thanks for your feed-back,
William
