The bib file from my biblatex-abnt style won't compile properly since I updated BibLaTeX to the latest version.
ABNT's rules are terrible and very inconsistent, so I do a lot of weird stuff in that file to try to replicate them.
Here's one example that doesn't work anymore:
\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{alves1995,
author = {Roque {\relax de\nopunct} Brito Alves},
title = {Ciência criminal},
location = {Rio de Janeiro},
publisher = {Forense},
date = {1995},
}
\end{filecontents}
\usepackage{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
\nocite{*}
\printbibliography
\end{document}
I can work around this particular example in other ways, but there are others, and I'm not sure what they have in common. Maybe the use of groups within entries? But sometimes that works. I don't know...
Also maybe the problem is related to this one somehow?
author = {family=Pinto, given=Carlos de Souza Carvalho, given-i=C {de\nopunct} S C}works but is inconvenient. – moewe May 28 '18 at 19:21
