Hey,
I have following document:
\documentclass{article}
\usepackage{lipsum}
\begin{document}
test
\end{document}
I run
lualatex -ini -jobname=mwe "&lualatex" mylatex.ltx mwe.tex
I get
This is LuaHBTeX, Version 1.21.0 (MiKTeX 25.2) (INITEX)
...
(C:/MiKTeX/tex/latex/l3backend/l3backend-luatex.def)))
! Use of \??? doesn't match its definition.
<argument> \???
! LaTeX Error: Access to an entry beyond an array's bounds.
l.208 }
When doing the "same" with pdflatex, it works:
pdflatex -ini -jobname=mwe "&pdflatex" mylatex.ltx mwe.tex
Can there be something done about this or is lualatex inherently
incompatible with mylatex as somehow indicated at
https://tex.stackexchange.com/a/83486/9075?
Cheers,
Oliver
