Here is the correct code:

static void callalert (lua_State *L, int status) {
  if (status != 0) {
    lua_getglobal(L, "_ALERT");
    if (lua_isfunction(L, -1)) {
      lua_insert(L, -2);
      lua_call(L, 1, 0);
    }
    else {  /* no _ALERT function; print it on stderr */
      fprintf(stderr, "%s\n", lua_tostring(L, -2));
      lua_pop(L, 2);  /* remove error message and _ALERT */
    }
  }
}
