UIKit _wrapRunLoopWithAutoreleasePoolHandler + 36: sometimes happens from Crashlytics report

Question

I received this crash report from Crashlytics

UIKit _wrapRunLoopWithAutoreleasePoolHandler + 36 

And this happened only once from all users of my application, and I had never seen this crash before when it is in the debug version.

From the search, this is due to too much “release”, but my project actually uses ARC and the entire third-party module, all of them ARC. Only one module that I found that still has non-ARC is MBProgressHUD. But it calls "release" in dealloc () and C # ifdef! _has_feature (obj_arc). Therefore, the release should not be called at all. Here is the code

 - (void)dealloc { [self unregisterFromNotifications]; [self unregisterFromKVO]; #if !__has_feature(objc_arc) [color release]; [indicator release]; [label release]; [detailsLabel release]; [labelText release]; [detailsLabelText release]; [graceTimer release]; [minShowTimer release]; [showStarted release]; [customView release]; [labelFont release]; [labelColor release]; [detailsLabelFont release]; [detailsLabelColor release]; #if NS_BLOCKS_AVAILABLE [completionBlock release]; #endif [super dealloc]; #endif } 

Can I conclude that this crash accidentally happens? Because not my code calls "release" (my application still has a relatively small user base)

Thanks in advance
