I did this now and it reports your example PDF correctly as unencrypted.

Do you have a backtrace of the crash on linux? Might be worth debugging. That
the build fails in the latter case is fine. PoDoFo currently definitly
requires Fontconfig. I don't think you need font support though for your
problem. So it might be an option to add preprocessor defines to make
fontconfig or font support in general an optional feature so that you can
compile PoDoFo without fontconfig if needed.

Ah, I think you are right. It should get deleted in the destructor of
PdfDocument.

I think it is better if you send these important issues to the mailinglist. So
maybe Craig and Leonard can have a look on your stuff and issues, too. They
are more experienced especially regarding the fontconfig/font issues.
In general chances are higher that we can help faster if more people can read
your questions.
best regards
