First-chance exception on closing RRS feed

  • Question

  • The symptom is:

    First-chance exception at 0x7703f9f2 (ntdll.dll) in ....exe: 0xC0000008: An invalid handle was specified.",

    occurring after the Form has closed. The top of the call stack is:


    The project is dual native C++ and C#. I have no idea of how to determine where this bug originates. Is there a way to find out who owns the handle? Anyone have a clue?

  • Misalignment of the stack at the end of a method execution *when returning from a function) is usually caused by the return parameter of a method not being the same size in the called method and its parent.

  • How could this happen? I'm starting to think there's a bug in VS2013. If I generate a Windows Form project, compile and start debugging, then I get the "invalid handle" exception on exit. Not a single line of my own code was involved. If I run a mixed project with native debugging enabled, then this generates a couple of annoying dialogs when exiting. I guess I could turn it off, but I *do* want to be alerted to my own bugs. I probably should move this inquiry to Microsoft's bug report page.

    Hi Frode,

    Thank you for posting in the MSDN forum.

    As far as I know generally the First-chance exception is not the app code issue.

    Maybe you could get useful information here:



    If you want to disable it, see:

    Actually this forum is to discuss the VS IDE, if you really submit a report for this issue here: https://connect.microsoft.com/VisualStudio/feedback/CreateFeedback.aspx, you’d better share a simple sample in your connect report, so it would be helpful for the product team experts to troubleshoot/repro this issue. Thanks for your understanding.
