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. :-)
