Hello

We have a crash report, which says Message: Exception EXC_BAD_ACCESS, Code 1830302080, Subcode 8 Attempted to dereference garbage pointer 0x16d183180.

and in the stack it's only 

"error": {
      "signalName": "SIGBUS",

                "Library": "raygun4apple"
           }
      ]
 },

My question is: is this likely a crash caused by raygun4apple/kscrash or it's something in our app, but the error report has failed to be generated?
