For some systems, once you hit a seg-v, things can't get any worse
Oh, yes they can! You could now be executing a virus. *Anything* the software is connected to can now do anything wrong or malicious.
(On my car, I installed an oil pressure switch that shuts off the electric fuel pump if the pressure drops. I also pried a switch off of a junkyard Mustang that shuts off if it gets hit hard, I also plan on installing that to shut off the fuel pump. Think of those like a "seg fault" <g>)
so why not try to make things better by saving what you can?
Sure, you can try saving things, but you'd better hope that there was already a reasonably recent clean copy of your data.
To write safe & reliable software, approach it from "what can go wrong, will go wrong", not "I won't worry about that case, because it's unlikely."
