Of course - and the best solution is to never have bugs in the first
place. ;-)
Seriously though, even if you're going to save data to an emergency
save file or something, this is the way to go. The more code you
execute before saving the data, the bigger the risk that whatever
happened before the segfault causing further data corruption.
Freeze - Save - Exit. :-)
