Yet another which is equally mysterious:

Faulting application name: Engine.exe, version: 1.0.0.0, time stamp: 0x4f4dee84
Faulting module name: KERNELBASE.dll, version: 6.1.7600.16850, time stamp: 0x4e211485
Exception code: 0xc03d0000
Fault offset: 0x0000b9bc
Faulting process id: 0x1414
Faulting application start time: 0x01ccf6c528f9f803
Faulting application path:C:\projects\AnalysisEngine\Debug\Engine.exe
Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
Report Id: 8a13fe4c-62b8-11e1-ab53-0050ba3279b5

More specifically, what is Fault offset? In what ways this information is helpful?


Solution

  • The fault parameter values are as follows:

    • P1: Process name
    • P2: Process version
    • P3: Process timestamp
    • P4: Module name
    • P5: Module version
    • P6: Module timestamp
    • P7: Exception code
    • P8: Exception offset from the start of the module
    • P9: Unused
    • P10: Unused

    The exception offset can then be used with a map and/or a cod file to determine at what point it crashed. A debugger attached to a running process will also allow you to see what is at that offset.

    Note that the parameter values are very similar to the values reported for .Net runtime crashes.
