<br>
The attached file 'refman.tex' seems to hit an endless loop in LuaLaTeX <br>
version 1.15.0 (TeX Live 2022/Debian).<br>
<br>
It is the heavily stripped-down version of a Doxgen file for the GiNaC <br>
system [1]. It requires three style files from Doxygen 1.9.4, which I <br>
haven't stripped down and which are attached to this email in their <br>
original form.<br>
<br>
Running lualatex in gdb suggests there is an endless loop somewhere in <br>
function test_ligature(lig, left, right) in file luatexdir/font/texfont.c.<br>
