I am trying to use this code: https://stackoverflow.com/a/14063081/1011125.
But on my iPhone 4 (iOS 7), this part let's the whole app crash:
dispatch_queue_t queue = dispatch_queue_create("cameraQueue", NULL);
[output setSampleBufferDelegate:self queue:queue];
What's wrong with this little snippet?

When I run my iOS app in Xcode & test it on my device (before submitting) it returns no errors and it works flawlessly. But when I test the app after the update to the app store, it crashes every time I open the app on my device. I get the following error in my crash log:

I have tried opening on multiple devices & the same thing occurs. What should I do to resvole this issue?
From the look of the log you probably have the default Core Data stack in your code, and in the update modified your object model. You then have problems with migration on an version update. There in the Core Data template there is a nice call to abort() in the
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator
method. There is a nice long comment about how it shouldn't appear in production code and some ideas on migration. I'd take a look in that method and verify the abort() is gone.
Just released this morning an app that I tested on all possible devices and simulators, but when I downloaded it from the store the application crashes at startup. I have tested it on many devices and iOS versions, but the result is the same:

The problem is only happening to me or is the same as last month: that is a problem of apple server that sign apps?
I solved the problem: changing the language from Italian (my native language) to English, the application works properly. This explains why the AppReview Team has not noticed the crash, and was due to a missing localization in a xib file: "Could not load NIB bundle: 'NSBundle (loaded)' with name 'MasterViewController'"
Im trying to integrate Brad Larson's GPUImage framework to my project. The sample code works fine. After I've intergrated, it builds fine but Im facing crash while running it. It crashes at AVCaptureVideoDataOutputSampleBufferDelegate method,
- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection;
Particularly at
runOnMainQueueWithoutDeadlocking block. I tried to find out the crash area but couldn't find it even after some few hours of time on seeing the crash log too. I didnt get any idea about the crash. Below is the crash log of Im getting on it. Can some one point me out the issue in it? I also have a doubt that, can I use to continue the queue in name com.sunsetlakesoftware.GPUImage.processingQueue?

Finally, I found the solution. I just replaced the compiler flag of the AppDelegate in target's compile sources which is set for the purpose of ARC.
i.e. I removed the -fno-objc-arc flag and replaced it by -fobjc-arc flag for the AppDelegate class which caused the crash.
I met a strange problem
I am using a NSURLConnection to do some URL request
it work fine on simulator
but it crash on ipad2 5.0
I've tried on iPad1 5.01 ,ipad2 4.33,ipad2 5.01, it worked fine
just crash on ipad2 5.0
I'm not sure what problem is
it seems something wrong with
[NSURLConnection(Loader) _resourceLoadLoop:]
I thought maybe NSURLConnection's delegate may be destroy before NSURLConnection do it's job
so I make retain with the delegate,but still crash
does anybody know what may cause this problem?

When the crash logs say "Highlighted Thread:" it may still be a different thread. It is not sure.
All threads except thread 0 (main thread) seem to be stopped at waits or traps. Since thread zero is the only one that appears active, it is the real source of the crash.
Since thread 0 does have main() or UIApplication at the bottom, the stack is probably corrupted or it is in some system functions which use a non-standard way of building stack frames.
Here is the Crash report can anyone help me identify whats actually going on.. If you need anything from me please let me know.. Thank you

In Xcode open Organizer window and go to Devices tab and Select Device Logs under Library section. Import the crash log if its not present in Organizer window and clock on the Re-Symbolicate icon at the bottom. You can see some changes in the crash log file. Then check the lines representing your app name(Womp Womp App). The hex-values in the right will be replaced with something like 0x0000216a +[MyCrashedClass myCrashedMethod:] (MyCrashedClass.m:<lineNumber>).
Check the line number in the crashed class, and that will be the crashed point in your app.
