You can do this in your panic or terminate handler. It's functionally the same error handling strategy, just with a different veneer painted over the top.

Crashing is bad, but silently continuing in a corrupt state is much worse. Better to lose the last few hours of the user's work than corrupt their save permanently, for example.

Hopefully crashing on unexpected state rather than silently running on invalid state leads to more bugs being found and fixed during development and testing and less crash-prone software.

So you don't get a crash log? No, thanks.

- The user may have unsaved data

That should not need to be a consideration. Crashing should restore the state from just before the crash. This isn't the '90s, users shouldn't have to press "save" constantly to avoid losing data.
