OK, G_LOCK (object_name_mutex);
expands to
  ((g_threads_got_initialized) ? (*g_thread_functions_for_glib_use . mutex_lock)
 ((((*((gpointer*)&g__object_name_mutex_lock)) ? *(&g__object_name_mutex_lock) :
 g_static_mutex_get_mutex_impl (&g__object_name_mutex_lock)))) : ((void)0));

I have also found that this "type-punned pointer" apears only with -O2 (or
greater). My GCC version is
gcc version 3.4.4 (mingw special)

You are right, it is probably a GLib bug, I will report this to their bugzilla.
