Reachability crashes every time network changes status

Question

My app crashes every time the network status changes from no network to network or vice versa at the following line with EXC_BAD_ACCESS:

    dispatch_async(dispatch_get_main_queue(), ^{
        [[NSNotificationCenter defaultCenter] postNotificationName:kReachabilityChangedNotification 
                                                            object:self];
    });

Im calling through app delegate using:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(checkNetworkStatus:) name:kReachabilityChangedNotification object:nil];

    internetReach = [Reachability reachabilityForInternetConnection];
    [internetReach startNotifier];
    [self checkNetworkStatus:nil];

and

-(void) checkNetworkStatus:(NSNotification *)notice
{
    // called after network status changes
    NetworkStatus internetStatus = [internetReach currentReachabilityStatus];
    switch (internetStatus)
    {
        case NotReachable:
        {
            NSLog(@"The internet is down.");
            break;
        }
        case ReachableViaWiFi:
        {
            NSLog(@"The internet is working via WIFI.");
            break;
        }
        case ReachableViaWWAN:
        {
            NSLog(@"The internet is working via WWAN.");
            break;
        }
    }

}

Anyone know how to fix this?

This might help you: Reachability Classes crashing program - not sure why

I had a problem with deallocating Reachability objects on a different thread to the one they were created on. I see you're allocating Reachability on the main queue, are you deallocating there too?
