# LuaTeX bug? Abrupt stop

I'm on Windows, with latest and fully updated MiKTeX. I try to compile a document with lualatex test.tex where test.tex is

\documentclass{scrartcl}
\usepackage{fontspec}
\begin{document}
code
\end{document}


LuaTeX stops without any error message. In the console it says

("D:/Program Files/MiKTeX 2.9/tex/luatex/luaotfload/luaotfload.sty"(using cache:

C:/Users/M├írton/AppData/Local/MiKTeX/2.9/luatex-cache/generic)
Sorry, but lualatex did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

C:/Users/M├írton/AppData/Local/MiKTeX/2.9/miktex/log/lualatex.log


but because my username has accents in it, the mentioned log file is in fact in

  C:/Users/Márton/AppData/Local/MiKTeX/2.9/miktex/log/lualatex.log


and its contents are

• The miktex binary won't work with the current luaotfload. You could try the newer luatex from the next repository miktex.org/announcement/miktex-next-5900. You will then also need the Luaotfload v2.7-fix-1 from here: github.com/lualatex/luaotfload/releases (I don't know if it will solve your name problem). There you can also get the older luaotfload 2.6. Apr 28 '16 at 18:27
• @UlrikeFischer or wait for the bugfix... so it is indeed a bug. I'll use XeTeX for now. Thanks. Apr 28 '16 at 18:36
• Bugfixes don't happen out-of-blue. Someone has to report the problem. Apr 28 '16 at 18:47
• @UlrikeFischer is it a MiKTeX or a LuaTeX bug? where can I check if it's reported already and report it if not? Apr 28 '16 at 18:49
• Imho there wasn't a update of some binary, only luaotfload. So if there is a bug it is probably in luaotfload. But you will have to test it with the new luatex from miktex next. Or find a texlive 2016 pretester with such an user name. Apr 28 '16 at 19:24
