#2 Problems using Standalone after update

[Julian Dobusch]

I have a problem using standalone. I described it in more detail here (see Edit2): https://tex.stackexchange.com/questions/565269
Basically when using standalone I get

(./file2.tex ! Missing number, treated as zero. = l.11 \end{document}

The same example code works on another machine not updated as recently so I'm wondering if this might be related to a recent update (which I did before the error occured) or that the update broke my installation.

A simple example is

\begin{filecontents}[overwrite]{file2.tex}
\documentclass{article}
\begin{document}

    blub

\end{document}
\end{filecontents}
\documentclass[]{report}
\usepackage{standalone}
\begin{document}

\input{file2.tex}

\end{document}

It fails only with lualatex (which uses a different implementation of a string comparision command). The problem seems to be the \aftergroup\endinput in \sa@enddocument which interrupts the command. I will also open an issue about the string comparision command, perhaps this need a correction.

According to Ulrike Fischer is problem is: \aftergroup\endinput in \sa@enddocument is too early now, it interrupts the hook code

the problem has been resolved in l3kernel, the document compiles for me now. https://github.com/latex3/latex3/issues/813

Closed as the problem got fixed upstream (LaTeX core).
