What is your preferred method to return from a segfault?

i.e. define

do_segfault()
 

If I understand your question right...

A segfault is the best possible behavior that you can get given undefined behavior, because it's a specific runtime error that you can probe. You're actually not guaranteed to get a segfault when your code has undefined behavior.

Thus, it is both technically impossible and entirely unwise to "recover" from a segfault. Let the program crash (did we have a choice?), figure out what in your code is undefined behavior, and fix it.

To put that another way, because a segmentation fault is a runtime error, and one that isn't guaranteed anyhow, it's immune to try-catch statements and error handling.
