The Blue Screen Of Death Pass To iPhone 5S

Who don't know the famous Blue Screen of Death on Windows devices, and who didn't face this annoying problem between windows users.
But it seems that the infection pass to apple new iPhone 5S.
According to some iPhone 5S users, the Blue Screen of Death appear when they launch the Numbers App in Apple's iWork Suite (which come for FREE with the phone) then the device restart automatically.

This problem is not recent, we can say it come with the phone since the first day they got it.
It's noted that the most of apps crash on iphone 5S more than any other iPhone so the question here, do we will see a solution from apple ? or this is a bug in this expensive phone.
