Debugging an iPhone crash report

Question

Debugging an iPhone crash report

How do I debug the following crash report?

A user installs the App from the App Store but the App crashes when loaded. I cannot re-produce the crash myself. I went to my crash reports on my own iPad and found a similar one, but again, cannot re-produce it. The problem is for the user that it prevents the App from loading (whereas, the crash I found myself just crashed the App, but it works fine when restarted).

Is there anybody who can point me in the way to debug the below?

I suggest you do two things:

To integrate a crash reporting library such as Instabug will help you get more details about the type of device, software version, CPU load, memory usage, and connectivity. All of which are important factors when it comes to debugging and reproducing the crash.
Your crash reports are not symbolicated. You first have to locate your project’s dSYM file. Below is the fastest way to locate your project's dSYM
```
mdfind "com_apple_xcode_dsym_uuids == your-UUID-here"
```
Your UUID can be found on top of Instabug's dashboard.
You can then upload your dSYM file through the dashboard so you can get more comprehensible crash reports.

For full disclosure, I work at Instabug. Let me know if I can help.

The crashing thread 10 has only Apple framework calls, nothing from your app. Those will symbolicate if the symbolication script has the iOS 5.0.1 symbols accessible via Spotlight. Your apps dSYM won't help for that stack trace.

Since the exception type is SIGSEGV you won't find a line number in the crashing thread which causes the crash. You have somewhere (could be anywhere!) in your code a memory problem, which causes the app trying to access a memory address which is actually invalid. Hence, causing the crash.

Symbolication of Thread 10 gives in the following result:

Thread 10 Crashed:
0 libobjc.A.dylib                   0x31516fbc objc_msgSend + 16

9 libsystem_c.dylib                 0x35e5ead0 thread_start + 0

obj_msgSend is another hint to the memory issue, and it looks like this happened after you started some code in a new thread. So you might want to check those places in your threading code. Maybe you are accessing an ivar that is already released in another thread.

In general the best way I found to reliable find and resolve memory issues was using a testing framework and automate the app interaction so it runs a long time. It also helps to automate it by redoing the same user interaction over and over again. It will most likely crash, but this time reproducible so you can run the automation with instruments aside. I did use the KIF framework with great success for that.

What you want is to symbolicate your crash reports.

These couple of links may help you somewhat.

http://kevincupp.com/2011/05/12/symbolicating-ios-crash-logs.html

http://www.buildingiphoneapps.com/2011/03/processing-users-crash-logs-when.html

If you have not saved the .dSYM for that build, of are not able to symbolicate the crash, then you should start doing so from next release onwards, so that you may understand the crash reports next time.

Is this crash report in your Xcode organizer? If not put it in there, and see if it symbolicates it, will give you more information about where the crash occurred.

it's maybe happened when you release more time or use object after release it.

check your source code.
