Appstore app works perfectly on iPhone 3GS but crashes on iPod Touch and iPhone 3G on launch

Question

I developed an app with Xcode 3.2.3 and iphone SDK 4.0, it works fine on both iPhone 3GS and 3G if I run it directly with xcode.

However, if I download and install the app from appstore, it crashes at the launch screen for iPhone 3G and iPod Touch. (But works on 3GS with OS 3.1.3 or iOS 4.0)

The device log shows the following:

Exception Type:  EXC_BAD_INSTRUCTION (SIGILL)

Exception Codes: 0x00000001, 0x00000000

Anyone knows how to fix this? Thanks!

Answer 1

You have the wrong architecture setting in your Release configuration. If you want to deploy on a 3G and 2008 iPod touch, you must create instructions for arm6 and arm7. You are probably creating an optimized arm7 binary only. Add the arm6 architecture to your Release configuration and try again.

Answer 2

I figured it out by referring to info on this page: http://useyourloaf.com/blog/2010/4/21/xcode-build-active-architecture-only.html

If you are using any third-party libraries, should recompile all of them using the same project settings as you used on your own project.

In my case, Base SDK: iOS 4.0, Deployment Target: 3.0, and make sure you uncheck "Build Active Architecture Only"

Answer 3

Hey noear, I'm having the same issue but I still can't seem to figure this out, can you please help, I must be missing something...

My app works on iPhone 3GS and 4 with 4.0/4.01 installed, however it still crashes at launch on iPhone 3G that has 4.0/4.01 installed. It works fine on Debug Mode

My settings are pretty much the same you described above.

Configuration: Distribution Architecture: Standard (armv6 armv7) Base SDK: iPhone Device 4.0 Build Active Architecture Only: Unchecked Valid Architectures: armv6 armv7 Deployment Target: iPhone OS 3.0

I use Facebook-three, and I recompiled the whole project with the same settings

any idea? Thank you very much!

Answer 4

Hi KTS,I get the same problem as you. Have you sorted this out? please help!

Answer 5

The start-up crash is a result of the wrong architecture for the dependencies and your project. I had a similar issue with my project. My project was running fine on Debug iPhone 3G, and crashing Release iPhone 3G. However, it ran fine on iPad and iPhone 4 in Debug/Release.

I had a library that I was building with Debug (Standard armv6, armv7), and the Release (Optimized armv7). The main project was building with Standard (armv6, armv7) for Debug/Release. This architecture mismatch caused the crash in Release on iPhone 3G. The reason I had this crash is that iPhone 3G must use armv6, but iPhone 4 and iPad can use armv7.

To fix the issue change the iPhone library Target's "Architectures" to use Standard (armv6, armv7) for "All Configurations".

Hey, you've mentioned using Facebook three20 library. We had exactly the same problem - application crashing with EXC_BAD_ACCESS only in appstore distribution | release configuration, ONLY on iPhone 3G / iPod touch 2G, but working perfectly on iPhone 3GS and iPad. It turned out that we were using JSON library built-in three20, and that library was the cause. Problem solved by downloading new version of JSON library (apparently with this error fixed) in our case.
