I recently enabled BugSense in my App to try and help gather crash reports. I’m seeing a lot of crashes that look like they are happening immediately upon startup of my App (I haven’t been able to replicate on any of my own devices). The problem is that the stack trace I’m getting from BugSense makes it look like my App actually isn’t doing anything to cause the crash. All I see is the very first main call to start the AppDelegate in the trace and then a bunch of libs that don’t symbolicate well.

I realize this might be not enough information to figure out my crash but perhaps I can get help with being pointed in the right direction. I can’t replicate on my own devices (and several other people’s devices), and the stack-trace from BugSense is from the released App out in the wild.

This is the stack trace that BugSense has given me.

I’m using instructions from, Atos cannot get symbols from dSYM of archived application , to symbolicate. It has worked for other stack traces where I actually see some of my code causing the issue just doesn’t really give me any information for the above trace.

    That crash report won’t help a lot, you need the last exception backtrace to see what parts of your code are causing the crash. As you see in the stack trace, the exception is rethrown, so happened in another runloop.

    A newer version of PLCrashReporter, which BugSense crash reporting is also based on, provides that. http://code.google.com/p/plcrashreporter/

    Side note: The service HockeyApp.net uses the latest version of PLCrashReporter in its open source SDK (QuincyKit.net) providing last exception backtraces and symbolication on the server. (I am a member of both)
