Exception Codes: KERN_PROTECTION_FAILURE at 0x00000008

Hi All,

I am developing a navigation based application. This application uses map kit and core location framework mainly. My application is running in 1generation phone with iPhone OS 3.0 but when I try to run this application on iPhone 3GS then it crashed. The crash log file comes with following error
