Since an upgrade to iOS 10 we have a lot of customers that experience undesired behavior in that our app is crashing up to 4-5 times a day. We use Xamarin Insights for our crash reporting. All the crash logs show the same nano_vet_and_size_of_live error crash. Here are a few examples.

We can't find any solution to this. In the background we make use of a lot of CFRunLoop. The crashes seem to be in random parts of our code and on iOS 9 the code was working like a breeze. The problem is that new customers get iOS 10 with their new iPad Pro's out of the box.
These guys seem to have the same problem, but there is no response from Apple.

Is there any workaround to this crash? Can anyone help us or should we wait for iOS 10.2 and hope this problem is fixed?
