App crashes in iOS 5 and works fine in iOS 6 and 7

App works fine in iOS 6 and 7 but crashes in iOS 5. It is a universal app. I have two main xibs for iPhone and iPad. No storyboards used.

App crashes before even entering appdidfinishlauching.

I have enabled zombie and added all exceptions breakpoint. Deployment target is 4.3

Below is the device log:

Please help. Thanks in advance.

It is very hard (if not impossible) to tell from your log what exactly is causing the issue but we can tell what sort of error it is. It is throwing a EXC_BAD_ACCESS exception which is basically an error in your memory management.

The best way to debug this is to turn zombie tools (NSZombieEnabled) on. This is located in xcode >> Product >> Scheme >> Edit Scheme >> Diagnostics and check the check box Enable Zombie Objects.

What EXC_BAD_ACCESS is saying is that you did something that caused a pointer to be de-referenced and that memory location isn’t inside one of the chunks of memory assigned to your program.

This could be because

1. The pointer used to point to memory that was ok, but its chunk was deallocated.
2. The pointer is corrupt.

In simple terms you are trying to access something that has been deallocated from memory. Unfortunately we don't know where this is from what you have posted. So for you, you need to be doing so debugging to replicate this issue. That is all you we can't help with that.
