I have no idea how to transpose the following latex example to
context. Also in my opinion the input is wrong, it should be written
as \mathtestbase{fb}^{-1} (and this works fine).
So I'm only posting this for the case that it indicates some hidden
problem in the fontloader.
The error I get from the document below is
! error: (nodes): attempt to double-free math_char node 100300,
ignored
! ==> Fatal error occurred, no output PDF file produced!
The fonts used are
[latinmodern-math.otf]:mode=base;script=math;language=DFLT;
and
STIXTwoText:mode=base;script=latn;language=DFLT;
Imho the relevant points to trigger the error are
- a math alphabet which uses mode=base
- a ligature in this font (fb here)
- a following math symbol directly behind the ligature (\int would
give an error too).
\documentclass{article}
\usepackage{unicode-math}
\setmathfontface\mathtestbase{STIX Two Text}[Renderer=Basic]
\begin{document}
$\mathtestbase{fb^{-1}}$
\end{document}

The original error was from a hidden \mathrm. > (i don't see a fb lig in that font > (unless i have the wrong font of course)) Ups. I get the error but only with a version which resided in my windows fonts folder. When I force lualatex to use the version in the texmf it disappear. For the faulty font I see in the lua-file: [983055]={ ["boundingbox"]={ 18, -10, 830, 713 }, ["index"]=662, ["name"]="f_b", ["unicode"]={ 102, 98 }, ["width"]=865, }, The font used on my system is c:/Wi ndows/Fonts/STIX2Text-Regular.otf The original bug report (https://github.com/khaledhosny/libertinus/issues/166) mentions also Amiri and Libertinus Serif. With \setmathfontface\mathtestbase{Libertinus Serif}[Renderer=Basic] i get the same error and it too has a f_b ligature: [983076]={ ["boundingbox"]={ 22, -12, 741, 700 }, ["class"]="ligature", ["index"]=2438, ["name"]="f_b", ["unicode"]={ 102, 98 }, ["width"]=778, }, -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 9+ messages in thread

Good. Is this an engine or a fontloader issue? While discussion the issue with the unicode-math maintainer the question came up if mathalphabets like \mathrm etc should better use mode=node or mode=base.
