Even though this is an old issue I thought I'd post it here for others experiencing similar crashes.

This issue is happening due to concurrent network requests accessing/modifying the HTTPHeader dictionary in a non-thread safe manner. Newer versions of this library have fixed the problem by accessing & modifying the header dictionary through its own private queue so you can either upgrade your version of the library or if that is not practical, wrap your calls to modify and access the http headers with @syncronized {} or using a dispatch queue.

Can you mention the version where it got fixed? Currently i am using AFNetworking 3.1.0 and i have this issue.

Looks like this was fixed in #3526, which was released in AFNetworking 3.2. Can you try 3.2.1 and report back?
