So?  Are we worried about damaging our well-running program after it  
encounters a seg fault?

If 99.9% of the time, throwing an exception works on a segfault (which it  
should on a null pointer access), and every once in a while, it just  
crashes without a trace, I think we'd be much better off.

I personally think even if we don't throw an exception, but print a full  
stack trace, that would be fine.  Limit the stack trace to N frames to  
prevent an infinite loop when stack corruption has occurred, and I think  
we'd be good to go.
