Yeah, it was the fact that the CLLocationDegrees in the CLLocationCoordinate2D struct were doubles, or that CLLocationCoordinate2D was a struct.
The other possibility might be if the mapView.annotations array is nil terminated, that might cause the premature death.
Rebuilt the string and recreated the array and it's fine.
Still think that NSJSONSerialization dataWithJSONObject:jAnnotations options:NSJSONWritingPrettyPrinted error:&error should throw an error rather than just crashing. Seems odd to have the error option there, but not usable.
