StackOverflowException from PdfDocumentAnalyzer.AnalyzeSyntax

[Mark Oliver]

I have a problem that is occurring in a .NET Core 3.1 Console Application and an Azure function.  We execute the following code which will then crash with an exception being thrown.

       // Create a new instance of PDF document syntax analyzer.

       var analyzer = new PdfDocumentAnalyzer(pdfStream);

       // Analyze the syntax and return the results.

       SyntaxAnalyzerResult analyzerResult = analyzer.AnalyzeSyntax();

The PDF does not seem to be corrupt and is attached to this thread.

I have downloaded, through Nuget, the latest update to the Syncfusion libriaries and this problem still occurs.

The DLL throwing the exception is Syncfusion.Pdf.Portable.dll and this is reporting version 19.1.0.63.

Is this the version that is intended to resolve this issue?
