Why don't other programming languages have ranges?

Indeed, I'd like to know how you recover from a segfault without help 
from an external processes. Sometimes you know that some routine might 
fail once in a week, but the program MUST run non-stop for several 
months. In Java you can achieve this with exceptions. And you can also 
dynamically fix classes with the class loader.
