SIGSEGV crash on iOS, caused by _Z4bootiPPc - ios

I am trying to figure out this crash which was reported through crittercism for an app I am working on for iOS.
I've been searching for an answer, but without any luck.
The name of the crash is SIGSEGV and it is caused by _Z4bootiPPc.

App SIGABRT Crash

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.

iOS: App crashes due to a dispatch_queue

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?

iPhone app crashes on some devices upon startup, but runs on others

We migrated an iOS 6 app to iOS 7 without altering anything in particular beyond some minor adjustments. We tested the app on the 3, 4, 4S and 5S iPhones and reported no problem.
Now two users are reporting that the app crashes upon startup. I advised one of them to remove the app altogether and install again which resulted in the app running smoothly.
He forwarded the crash log to me but it's a little cryptic. Can anyone help me pinpoint the issue?

...
I would venture to guess your update included 64 bit update iOS7 + iPhone5 and your data might be formatted with incorrect formatter:
ie: [NSString stringWithFormat:#"Some foo %d"];
This might work with 32 bit int but it will fail on a 64 bit platform.
Are there any warnings when you compile your binary?
The reference to stringURL was indeed nil which resulted in the crash. This was due to a silly race condition.

Evaluating an iOS crash report (app built with phonegapbuild so can't symbolicate in xcode)

Below is the crash report from Apple.
Here is a web version of the app: http://www.web4uonline.com/yalecc/26/main.html
I built the app with phonegap build so I don't think I can have XCode evaluate the crash report any further than what is below.

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.
