Strange behaviour of \n in Macintosh XCode

[Hans van der Meer <H.vanderMeer@...>]

I am experiencing a strange behaviour in Apple Macintosh XCode when embedding Lua in it.

The relevant code is:

	lua_State *L = luaL_newstate(); luaL_openlibs(L);
	char *inputstring = "print('Hello!')";		
	int error = luaL_loadstring(L, inputstring);
	if (error == LUA_ERRSYNTAX)
		NSLog(@"Return from lua_loadbuffer = LUA_ERRSYNTAX \n");
	else if (lua_pcall(L, 0, 0, 0)) {
		NSLog(@"LUA-ERROR: %s\n", lua_tostring(L, -1));
		lua_pop(L, 1);
	}
	lua_close(L);

Running with inputstring = "print('Hello!')" is fine.
But with "print('Hello!\n')" luaL_loadstring generates a LUA_ERRSYNTAX:

	2011-07-01 14:51:39.932 EmbeddedLua[1371:a0f] Return from lua_loadbuffer = LUA_ERRSYNTAX 

I checked that \n has the value 10. Moreover, in the Terminal-application both prints are running without a problem. Also I checked that the program file is UTF-8.

Why does Lua generates a syntax error on encountering the \n?
Does someone has an explication?
