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 metamethod 'index'\n ...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:104: in function <...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:62>\n [C]: in upvalue 'builders_kernel_mlisttohlist'\n [string \"local tonut = nodes.tonut...\"]:43: in function <[string \"local tonut = nodes.tonut...\"]:18>\n (...tail calls...)\n ...ext/tex/texmf-context/tex/context/base/mkxl/math-noa.lmt:2986: in function <...ext/tex/texmf-context/tex/context/base/mkxl/math-noa.lmt:2984> My system is : FreeBSD 64bits Thank you for any help.
