core data delete crash

I need to update a task before it is deleted. I found when this line [self.fetchedResultsController objectAtIndexPath:indexPath]; is executed in NSFetchedResultsChangeDelete the app crashes.

  case NSFetchedResultsChangeDelete:{
        Task *task = [self.fetchedResultsController objectAtIndexPath:indexPath];
        [self deleleReminderForTask:task];
        [self checkForUpdateForTaskForDelete:task];
        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }

crash log:

CoreData: error: Serious application error.  Exception was caught during Core Data change processing.  This is usually a bug within an observer of NSManagedObjectContextObjectsDidChangeNotification.  *** -[_PFBatchFaultingArray objectAtIndex:]: index (40324416) beyond bounds (1) with userInfo (null)

Can anybody help me to fix this.

The fetched results controller has already been updated so you can't try to get the item from it. Instead you should use the object that is passed as a parameter to the delegate method. You should also check what you're doing with the deleted item is you still have issues.
