IOS 11 crash with VectorKit and Texture2D

Question

Since iOS 11 is available (from 11.0 to 11.0.3), we get these crashes. I can only assume that these failures occur when either the map display or the map tile is destroyed. However, we cannot reproduce the problem internally. Hockey reports this failure.

Given that this failure is always included in stream 0 (i.e., the main stream), we do not know where to start the investigation. This is “normal” for any UI related to setting up and tearing off the main thread, and not one of the broken frames in the stack contains a link to the code we wrote.

Has anyone encountered Texture2Dcrashes on dealloc?
