An application we wrote was crashing randomly on a customer's iPad Air that has iOS 7.1.1. Users running the app on other iPad types are not experiencing the problem. The customer sent us the crash logs by extracting them using iTunes and we found around 21 crashes all due to the following :
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000000000defe

The problem is that Xcode 5.1.1 is symbolicating correctly the crash log statements that lie in our application, but it is failing to symbolicate statements from the framework, hence we are not able to see why this thread is crashing.
Help much appreciated.
Update : The question that this has been marked a duplicate of solves the problem where the dSYM file is not properly loaded and the crash log is not showing the code in the application. I am able to see the statements in the app just fine since I have loaded the dSYM successfully and even checked the validity of the dSYM by cross referencing the UUIDs. My problem is that the framework statements (The code related to iOS SDK itself) are not getting symbolicated. I don't see where any answer in that question tackles that. Here is another thread that shows the application statements correctly symbolicated :
