Hi,
I've got an app where I'm joining together multiple PDF documents - this is working fine for the most part, but I am encountering some PDF documents that are causing it to generate an OutOfMemory exception.
I'm using PDFSharp 1.50 beta, and have a skeletal app illustrating the problem at
https://github.com/leighghunt/pdfsharp-test.
Has anyone else encountered this error - I assume it is to do with the "some files" alluded to by Thomas at
viewtopic.php?f=2&t=3017:

This works with many files, but some files still cause exceptions when you open them with PDFsharp.
An example of the error log is below.
Does anyone know of a workaround, or where perhaps I can download the source for 1.50 beta to investigate further?
