Hi @jamsharp!

I noticed that you posted several requests describing similar symptoms. As with the other topics, we would need the specific PDF files that reproduce the issue in order to investigate it properly on our side.

If you can share the affected files, it will greatly help us reproduce the problem and identify the root cause.

Thank you for being so cooperative!

@yuriy.mazurchuk

we would need the specific PDF files that reproduce the issue

Hi, do you really need them or could the callstacks already be sufficient?

I understand that it would be easier when we provide the files, but we got the exceptions from customers of us, and it might be hard to convince them to send us the files (which could contains sensitive information) and allow us to forward them to you.

[yuriy.mazurchuk]

As mentioned in the comment here

Most of these issues look like very specific data content issues or corrupted files. Because almost all call stack lines contain the sequence of calls, the ctor or loading from stream/file method.
That makes me guess about some specific cases with data content
