If it wasn't annealed at all, it would probably (I'd say definitely) crack before you put it back in the kiln for the second firing.
If it was poorly annealed, it might survive and it might not. A piece of glass might or might not survive if you dropped it on a cement floor, too, but the odds are a lot better if it has been properly annealed.

My memory is so good, I can't remember the last time I forgot something . . .
