Hi all, as another data point, the AUTH48 versions of the PDF rendering of RFC 8792 worked fine in evince. Viewing them in MuPDF did not produce any error or warning messages. The published version of the PDF does crash evince, and produce error and warning messages (as below) in MuPDF. As an obvious difference between the two files, the published PDF embeds the XML version of the RFC, while the AUTH48 versions did not.
