    Hi guys,
    We have an iOS app with the SDKs from Flurry and AdColony, built with Unity 4.6.3 p1 (IL2CPP enabled). Since Flurry has the crash reporting function, I watched the crash logs sent by users, and found many crashes are occurring at UnityAppController updateOrientationFromController while I have no idea how to reproduce them and can't submit a bug. It's in UnityAppController+ViewHandling.mm but the app doesn't support orientation change and is fixed at portrait. The below are the 2 kinds of stack traces as the top two culprits.

    My guess is these SDKs don't handle orientation correctly, but I'm not sure if just setting UnityAppController::updateOrientationFromController as NOOP can be a quick fix. Any idea?
