you are passing the beurk *adress* as second parameter into g_string_free,
this only works because the adress is != NULL and thus assumed as a TRUE
value.
the more correct approach would be:
g_list_foreach (list, (GFunc)g_string_free, GINT_TO_POINTER (beurk));
ut that is still ugly as a variety of platform have sizeof(void*)!=
sizeof(int). so the cleanes t way to do this is:

static void free_g_string (gpointer data,
                           gpointer user_data)
{
  g_string_free (data, GPOINTER_TO_INT (user_data));
}

g_list_foreach (list, free_g_string, GINT_TO_POINTER (TRUE));
