This problem is the same with both static and dynamic linking.
And lisp too!

Citation needed. I don't think my programs very commonly try to go completely outside their address space. The closest thing I see is null pointer crashes, which are still not very common, and those would work the same way in a shared address space.
Edit: Yes, fork doesn't work the same. That's a very narrow use case on the vast majority of machines.
