Hello,

Since ConTexT last upgrade (ltmx 2023.09.18 21:13), I have a document that
won't compile with ConTexT. The problem seems to occur when using mathcases
with some ConTeXt provided fonts, including pagella. This is a minimal not
working example :

\setupbodyfont[pagella]

\starttext
\startformula
\delta_{ij} =
 \startmathcases
 \NC 1 \NC \text{if } i = j \NR
 \NC 0 \NC \text{otherwise} \NR
 \stopmathcases
\stopformula
\stoptext

The error is :
run callback [44]:
...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:56: table index
is nil\nstack traceback:\n
...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:56: in

My system is : FreeBSD 64bits

Thank you for any help.
Sincerely,
