I know there are about 100.000 thread about EXC_BAD_ACCESS (SIGSEGV) Errors. But no one helped me out. I'm not able to solve my problem myself.
A few hours ago, I duplicated the target of my Xcode Project (a iPhone game) to make a free version. But since this Point I get very strange errors. Sometimes the app works as if nothing happened. But most of the time, I get errors like this:
Running pass 'X86 DAG->DAG Instruction Selection' on function '@gleLLVMVecPrimMultiRender13'
And the stack looks like this:

But the method called is not always the same. In this case it was [SMApplicationManager dealloc] and a few minutes ago it was [CCNode draw]. I can't get the source of this error. I think it has something to do with the second target.
Do any of you guys know anything more?
It's weird i got this error, and i went through countless solutions. Turned out, i had duplicated a line of code by accident. Just make sure when you duplicated, there is not code interfering with each other.
Finally after a few more hours of frustrating experiments I found the solution. The whole thing hadn't to anything with the second target. The Problem was the NSURLConnectionDelegate. In this class I implemented a Property named appID. And in one of the methods of the class, I set the variable without the setter. So I placed an autoreleased object at the position of a property. This one get released and the pointer to the variable gets invalid. As soon as the Delegate was released, a Method was sent to this yet released object.
But I can't explain why there appears this strange error Method. I haven't seen anything like that before. Can someone tell my why the error is called
Running pass 'X86 DAG->DAG Instruction Selection' on function '@gleLLVMVecPrimMultiRender13'?
