Depth of Field Crash on iOS 8 since 4.8

On iOS devices, specifically running iOS 8 or above, whenever depth of field camera is activated (by using the post process settings in the camera or using a post process volume) the game would crash straight away to home screen.

I’ve tried on my currently working project and also a brand new blank project. As soon as I activate the depth of field effect, the game crashes.

If I disable Metal support in project settings, then things seem to work, so I wonder if this is related to Metal?

I would like to include a game log, but I don’t know how to get the crash logs off my iPad.

Depth of field is working normally using UE4.7.6 on both iOS 7 and 8 (including using Metal).

Thanks!
