[NTG-context] gzip.compress in ConTeXt mkiv

Hi, The following document \directlua{ local arch = gzip.compress"I will become much much smaller, once the overhead is compensated" local orig = gzip.decompress(arch) print(arch:len(), orig:len(), orig) } \starttext \stoptext used to work in ConTeXt mkiv and still works in ConTeXt lmtx, but for current mkiv versions it breaks with ...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:610: attempt to call a nil value (upvalue 'tocardinal1') stack traceback: ...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:610: in upvalue 'putcompressed' ...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:662: in function 'gzip.compress' [ctxlua]:1: in main chunk Best regards, Marcel
