The stack shows 1070 repeated frames of:
- StructElementObject.ProcessChildPrimitive(...)
- StructElementObject.CopyPropertiesTo(...)
The StructureTree import is traversing a cyclic StructElement graph (or equivalent re-entrant child chain) without a recursion guard.
During this recursion, indirect object resolution repeatedly re-enters the same compressed object:
- reference.ObjectNumber = 554
- context.CurrentIndirectReference.ObjectNumber = 554
- TryGetIndirectObject(554, ...) == false at re-entry
PdfStreamWriter: Duplicated pages when merging documents with identical page content streams but different per-page Resources.
Workaround: Use the RadFixedDocument.Merge() method instead of the PdfStreamWriter.
In DOCX, such lines are defined using the legacy VML definitions:

Text frames are paragraphs of text in a document which are positioned in a separate region or frame in the document and can be positioned with a specific size and position relative to non-frame paragraphs in the current document. More information about it is available in section 22.9.2.18 ST_XAlign (Horizontal Alignment Location) of Open Office XML.
