Memory leak in StarBurn_DVDVideo_Create

I'm getting memory leak errors when using the StarBurn_DVDVideo_Create function to create a DVD image from a VIDEO_TS directory. I've simplified my function all the way down to where all it does is call StarBurn_DVDVideo_Create then immediately calls StarBurn_DVDVideo_Destroy and I still get three leak errors. I'm not allocating any memory on the heap myself, and the leak errors only come up when I call this particular function so I know it's not any of my other code, so it has to be a leak in the StarBurn SDK. Also, in case it helps, the three leaks are all 2048 bytes in length. (the same size as a DVD block)

What do you use to detect these leak errors? I've re-verified the code and did not find anything criminal... So more hints are required

Thanks!

Visual Studio 2005's debugger. I don't know if it matters or not, but I'm using the statically linked version of StarBurn and it's still running in freeware mode. (I plan on upgrading once I verify everything works correctly)

Here is the exact code I'm using...

Code:

      // Create DVD file system
      CString ExceptionText;
      ULONG SystemError = ERROR_SUCCESS;
      PVOID pDVDVideo = NULL;

      EXCEPTION_NUMBER ExceptionNumber =
         StarBurn_DVDVideo_Create(
            &pDVDVideo,
            "C:\\DVD\\VIDEO_TS\\",
            TRUE,
            ExceptionText.GetBuffer(1024),
            sizeof(ExceptionText),
            &SystemError,
            "VOLUMELABEL",
            "Publisher",
            "Application",
            2006,           // Year
            10,      // Month
            20,      // Day,
            12,      // Hour
            10,      // Minute
            0,      // Second
            50      // Millisecond
         );

      // Free allocated memory
      StarBurn_DVDVideo_Destroy(pDVDVideo);

and here is the output of the debugger when the program exits...

If I comment out that section of code then the leak goes away.

OK, should be reproducable in such a case. I'll give it a try during this weekend and would let you know about progress. Thanks in any case for pointing

We've build a test VS2005 project, put a sample directory with DVD-Video content and... there are no memory leaks at processing

Could you please try the version 7.2.20 (what's the version of the StarBurn you're using BTW) and issue us with a bit more information about what you do? Thank you very much for cooperation!
