aspose.Words v14.5 - Aspose.Words.Document Constructor StackOverflow

I have been trying to instantiate a Aspose.Words.Document with several different .docx and I’m getting stack overflow exceptions. I have attached an example file and below is the code snip…

case "doc":
case "docx":
case "dot":
case "dotx":
case "html":
case "mhtml":
case "rtf":
    Aspose.Words.LoadOptions wordOpt = new Aspose.Words.LoadOptions();
    wordOpt.LoadFormat = Aspose.Words.LoadFormat.Auto;
    wordOpt.PreserveIncludePictureField = true;
    if (switchVar == "doc") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Doc;
    if (switchVar == "docx") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Docx;
    if (switchVar == "rtf") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Rtf;
    if (switchVar == "dot") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Dot;
    if (switchVar == "dotx") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Dotx;
    if (switchVar == "html") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Html;
    if (switchVar == "mhtml") wordOpt.LoadFormat = Aspose.Words.LoadFormat.Mhtml;
    try
    {
        Aspose.Words.Document wordDoc = new Aspose.Words.Document(input.FullName, wordOpt);
        wordDoc.Save(output.FullName, Aspose.Words.SaveFormat.Pdf);
    }
    catch
    {
        throw;
    }
    break;

Hi Cary,

Thanks for your inquiry. After an initial test with Aspose.Words for .NET 14.10.0, I was unable to reproduce this issue on my side. I would suggest you please upgrade to the latest version of Aspose.Words. You can download it from the following link. I hope, this helps.

Best regards,

I have tried Aspose.Words v14.5-v14.10 (.Net 2.0 and .Net 3.5 builds.) and I have the same result… I have attached a new example file.

An unhandled exception of type ‘System.StackOverflowException’ occurred in Aspose.Words.dll
