EXC_CRASH (SIGABRT) crash error only for release version

The app that I have runs perfectly fine in debug mode but when tested in ad hoc in release mode a crash happens. The crash actually happens when the app first starts. I don't really know how to debug or proceed to find out what's the issue. Xcode doesn't throw any error.

The following is my crash log

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Update: After reading tonnes of stuff on the internet about symbolicating, finally I managed to do it with Xcode 5. Some were pretty complicated with the need to use the terminal. Luckily all I needed to do was to go to Organizer in Xcode, grab the latest Archive in Finder. Show Package Contents from that file to get the dsym folder. Copy it out to a folder together with the ipa file and then just install the ipa through Organizer. The crash log will look much more meaningful.
