Release build crash on attached device on first launch

[amatoria]

I have my iphone project with Login/Password as the first page after default splash screen. When I build & run the project's release configuration on attached iPhone it crashes immediately after (1 sec) the login view show up. No user interaction (user taps) with the app before the crash.

Points to note:
1. The same app doesn't crash every time after the first launch. That is, it work fine when i run it by tapping app icon on device.
2. Debug configuration runs fine all time even at first launch on device.
3. No issues while running the app on simulator in both configuration.

Any pointers about what could be the reason? Please help.

Thank you

PS: XCode v4.0, iOS sdk 4.3, iPhone 4 (iOS 4.2.1) and iPhone 3GS (iOS 4.0)

Please help !! I count on this forum for iOS issues.

Any idea after looking at both logs(console).

I tried creating fresh build config (Xcode 4), with only setting change, Build Configuration - Release from popup. [Run<app name>]

Otherwise can I send debug config'd app to Apple. Will they reject it?

[dany_dev]

mmm......what are you trying to do in didload?

For my surprise (or may be your surprise), I tried creating a brand new template project without doing anything in the default view controller, not a single line of code nor any change in nibs, still the release build configuration app crashes on first launch over device.

[dany_dev]

so there is something on your device that is not ok....for example if it is jailbreaked, backgrounder can create some problems.....

[smasher]

It's not a crash - it's perfectly normal. You can't "build and run" on the device with a release build because the debugger can't attach.

The key line is this one:

Sat May  7 19:46:43 unknown com.apple.debugserver-48[4339] <Warning>: error: failed to launch process (null): failed to get the task for process 4340

It couldn't start the app because the debugger couldn't get the process id - which is normal for release builds.

Thanks Smasher,

yea, probably that's the issue because in the past i always sent release to QC with code and provision file.
Thanks again.
