Yes, the components are all in different virtual address spaces. Anyway, I assume that changing the linking in such a way to get a components name would be like taking a sledgehammer to crack a nut. I wonder what exactly you mean with weird values (IP, stack pointer, pagefaults, ...?) and at where you are when observing them (Core, Kernel, debugger, ...?). I ask because, for example, the Region-Management code in Core actually knows which Address Space is used by which component. If your component causes a pagefault, Core not only prints the name of the component but also name and IP of the thread that caused it.
