This broke the compilation process on my machine. I just tested with a clean version of KDE Neon, Poppler 0.62, and it doesn't compile, something about FormFieldsSignatures.
Must also say that after I reverted back the commit, it compiled.
Is this only happening to me?
Edit: Tried with Poppler 0.76.1, still gave me error, error in the pastebin:
