Do you have any suggestions on where to start to look for the following crash:


-[AGSNSURLSessionDemultiplexer URLSession:task:didCompleteWithError:]
 -[NSMapTable NSMapTable { } ] count underflow


The full stack trace is:

Unfortunately, I don't have any steps to reproduce these, as I got them from Crashlytics.


Thank you,
