Hi all,
this is the most bizarre bug I've ever seen in context. I would be
grateful if others could try to replicate it. Test file:
\startbuffer[test]
<document>
<hskip width="1em"/>Materiam vati da Venus alma tuo.
</document>
\stopbuffer
\startxmlsetups xml:testsetups
\xmlsetsetup{#1}{*}{-}
\xmlsetsetup{#1}{document|
hskip}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:testsetups}
\startxmlsetups xml:document
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:hskip
\hskip\xmlatt{#1}{width}
\hskip\xmlatt{#1}{width}\relax
The file compiles cleanly if I give the --luatex switch.
Now for the bizarre part: if you delete the capital M of "Materiam" or
replace it by any other capital letter, the file compiles. What's going
on here?
Optional arguments (e.g. plus/minus values for \hskip) for commands are
handled different in LMTX but it was always recommended to add \relax
after the last value.
