Re: Feeding NSUnarchiver bad data can cause crash

I'd be very wary of trying that. The problem here seems to be a crash (segmentation violation, bus error, etc), which is most often caused by reading or writing data where you shouldn't. The errant code could have easily overwritten important data in your app before hitting an address to cause the crash. If you try to resume from where you started, you could be dealing with bad data (and worse, storing corrupt data back to some persistent store).

I worked on a high-traffic webserver program that caught SIGSEGV and SIGBUS and tried to recover, but it caused more problems than it was worth.
