Hi,

LuaTeX hangs in the following example, it is related to the optional argument for \startTEST. unrelated to luatex ... processbetween takes args one by one

and why did it work with pdfTeX?

i don't know ... maybe test with \tracingall and compare what happens

done, problem found. the following command in toks-ini.tex cause the freeze in mkiv: \def\dograbuntil#1#2% {\long\def\next##1#1{#2##1}\next} the correct definition should be \def\dograbuntil#1#2% {\long\def\next##1#1{#2{##1}}\next} Wolfgang
