PDFsharp & MigraDoc Foundation

Reporting an Issue Here
Incorrect number of pages found in a particular pdf.

More Info:
Pages aren't being detected in specific pdf. It only brings back 1 page, but there are 26 pages. I have tried debugging. It looks like the issue is related to the retrieval of iref. Based on what I am seeing, 8 0 R is the 1 page it is retrieving, then I believe 123 0 R are the additional pages which has kids inside of kids, but it looks like the iref value is null so it is removed during removetrailing. As a result, PageCount is 1 and number of page elements is 1.

Expected Behavior
Should find 26 pages. When saving, should still have 26 pages.

Actual Behavior
Finds 1 page. If saved, will only have 1 page.

Steps to Reproduce the Behavior
