Wikitude

Unity 7.1.1, Wikitude 7.0.0

In my game if I calibrate the instant tracker with the phone laid on the desk and then pick it up, the game crashes and I get this tty:

As SlamObjectTracker is mentioned I am assuming you will be familiar with the callstack.

I don't get any information when this happens with the debugger attached.

I tried this with the original Wikitude sample and got the same result although in this case it happens as soon as I press initialize.

I could not reproduce this behaviour on iOS.

Any clues as to how we can fix this?

I can confirm this is fixed in 7.1.0
