When luaL_setfuncs() is replaced by luaL_newlib() + lua_setglobal() in commit 74b3374, the commit did not take account that lua_setglobal() pops a value from the stack. Thus, following lua pop(l, 1) tries to pop from empty stack in Lua >= 5.2, especially in Lua 5.4, it causes abort(). This fix it. * miltertest/miltertest.c (main): Don't pop after lua_setglobal() in Lua >= 5.2 * opendkim/opendkim-lua.c (dkimf_lua_setup_hook, dkimf_lua_screen_hook, dkimf_lua_stats_hook, dkimf_lua_final_hook): As above.
