Application used MapKit crash on iOS6 - crash

Question

I have a strange problem with google map in my application dedicated for iPad (with iOS6). I've made a horizontal scroll view, filled with two views. One is a detail information view (some text, nothing special), and the second view is a view controller with google map. This is the universal scheme in my application (scrollview build from two views) for a few different purposes. The problem occurs when I've started to test the app on a real iPad with iOS6. The application crash when it should view a scroll view. But not immediatly. At start, scroll view is viewed properly. Then I want to build a new scroll view with new datas. It also goes fine, and scroll view is viewed properly. After a few operation like that I've start to receiveing more and more error logs like this:
failed to make complete framebuffer object 8cdd
After a few runs of scrollView, the application crash without any additional errors. Code editor points on main.m file, and the following line:
int retVal = UIApplicationMain(argc, argv, nil, nil);
Please direct me to find what am I doing wrong. Where is the viewDidLoad method from my view controller responsible for viewing the google map:
-(void)viewDidLoad {
mapView.mapType = MKMapTypeSatellite;
mapView.showsUserLocation = YES;
/* ANNOTATION (pin) */
CLLocationCoordinate2D annotationCoord;
annotationCoord.latitude = [self.restaurant.latitude doubleValue];
annotationCoord.longitude = [self.restaurant.longitude doubleValue];
// a pin with the info.
MKPointAnnotation *annotationPoint = [[MKPointAnnotation alloc] init];
annotationPoint.coordinate = annotationCoord;
annotationPoint.title = self.restaurant.name;
// add annotation to the map
[mapView performSelectorOnMainThread:#selector(addAnnotation:)
withObject:annotationPoint
waitUntilDone:YES];
[annotationPoint release];
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance (annotationCoord, 500, 500);
[self.mapView setRegion:region animated:YES];
[super viewDidLoad];
}
and no mater how I push the view controller with google map to the view. It always crash my app :(. I`ve tried like this:
[scrollView addSubview:self.googleMapViewController.view];
or that:
[[self navigationController] pushViewController:self.googleMapViewController animated:YES];
When I run the application on simulator, there`s everything all right. I'm using XCode 4.5.1.

I had the same problem in one of my projects. It was caused by a memory leak. Map views consume alot of memory if you don't delete them. It doesn't appear on simulator because a computer can use much more memory.
Just make sure to get rid of the map views when you no longer need them.
I also recommend running the app with Instruments (Leaks) - it is an extremely useful tool in such cases.
