I have absolutely no idea what is uninitialized there, as the line in question contains a call to luaL_openlibs(gL.T) after gL.T has been created by lua_newstate(). Thus it could even be possible that it's something internal to Lua itself. In any case this part hasn't changed for a while so if there's an issue there it's not new and we should not delay 2.0 just for this. > or should we ignore it ? Not yet, it still deserves some analysis I think before knowing if we can safely ignore it. Willy
