Facebook iOS SDK Crashes

Question

We experience many crashes in our application (Reporting by Crashlytics, but the developers could not reproduce). The stack trace suggests that this is caused by facebook sdk (3.15.1). Is this a known issue in older versions?

We are trying to figure out whether to send a new version with the latest version of the SDK or explore it further.

If you are using cocoapods, make sure that you have correctly configured the podcast version.

ie: the line in which your application is running

 platform :ios, '7.0' 

The line that your application is working with uses the OSAtomicDecrement32 method, which has a different implementation for iOS 7.1 and higher.
