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
