OS: Arch Linux (6.3.7-arch1-1)
LibreOffice: 7.0.4.2

I am encountering a stack overflow when using api.AddWatermarksFile, on a .pdf file which has been converted from .docx using libreoffice. Unfortunately I cannot share the document as it is sensitive, but I can say it contains a mix of text and images.

Not sure if related to #185

Running pdfcpu validate --v input.pdf produces (only adding the summary part here):

Empty free list.

Total pages: 33
No font info available.

No image info available.

validation ok

Relevant code:

	watermark, err := api.TextWatermark(text, "pos:tc,rot:0,points:11,scale:1 abs,color:#616161", true, false, types.POINTS)
	if err != nil {
		return err
	}

	api.AddWatermarksFile(
		inputPDF,
		inputPDF,
		nil,
		watermark,
		nil,
	)

The stack trace:
