Summary:
When interacting with a navigation controller on the iOS 8.1 64 bit runtime, UINavigationController does not throw an assertion failure when popping to a view controller which is not in the navigation stack.  The assertion failure does occur in the 32bit variant of the same runtime version

Steps to Reproduce:
1. Create a navigation controller with more than one controller on the navigation stack
2. call -popToViewController:animated: with a viewController not in the navigation stack

Expected Results:
expected an assertion failure to occur

Actual Results:
assertion failure only occurs on 32 bit iOS 8.1 runtime, with message:

'Tried to pop to a view controller that doesn't exist.'

On 64 bit iOS 8.1 runtime no assertion failure occurs.

Version:
Version 6.1 (6A1052c)

Notes:


Configuration:
Problem occurs on iOS 8.1 64 bit simulator
