Hi everybody, First of all, my best wishes of a very happy new year to all users of this list ! I used to update context standalone with the script ctx-update : cd /Users/rolandthiers/context rsync -ptv rsync://contextgarden.net/minimals/setup/first-setup.sh ./first-setup.sh --modules=all --engine=luatex Usually the update runs well, no problem. But the last time it did not work. I've got this message : This went wrong: ...67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en.lui:107: bad bytecode register This is LuaTeX, Version beta-0.78.0-2013123119 (rev 4704) \write18 enabled. . <*> cont-yes.mkiv ? Assertion failed: (kpse->program_name), function kpathsea_var_value, file ../../../source/texk/kpathsea/variable.c, line 36. mtx-context | fatal error: no return code, message: luatex: execution interrupted My system : Mac OS X 10.6.8 . Could someone tell me what happens or what mistake I did ? Roland
