Stack empty

I’m using the following libraries to convert a Word document into a PDF document.
Aspose.PDF =
Aspose.Words =

I receive the Stack empty error message, when I try so save the Word document in the Aspose.Pdf format.

I narrowed the issue down to one particular embedded Visio Object. The document contains about 10 different other Visio Objects which are not a problem when converting.

Can you please look into this issue?

Thanks a lot!

Thank you for your interest in Aspose products.
I have reproduced this issue and logged as #3959 in our defect database. As a workaround I managed to copy this OLE object and paste it to a new document. Then it became convertible. Maybe reconstructing the document, reinserting the object could help you. Our developers will take a look shortly and let you know in approximately 2-3 weeks about the progress.

We have released a new version of Aspose.Words that contains a fix for your issue.
The new version of Aspose.Words is available for download from here.
Best regards.
