Bug in g_module_close()?

I have some plugins which are loaded using g_module_open(), and later
closed with g_module_close().  The modules all have defined within
them:

const gchar *
g_module_check_init (GModule  *module)
{
   // Stuff is registered with the main app using uterm_control_register()
}

void
g_module_unload (GModule  *module)
{
  g_fprintf(stderr, "module unreg0: %s\n", g_module_name(module)); // Segfaults
  uterm_control_unregister_module_internal(g_module_name(module));
}

While g_module_check_init() is running, and before I call
g_module_unload(), I can call g_module_name() to get the name of the
module.  The name is used to track which objects are owned by the
module, and I use this in the module cleanup.

However... g_module_name is returning neither a NULL pointer nor a
NUL-terminated string while using the module structure passed to
g_module_unload(), which seems odd.  Prior to the unload, it returned
"/tmp/g/lib/uterm/0.1.0/modules/libiso646-c0.so", if I call
g_module_name in g_module_unload it trashes the stack and segfaults.

Is this a bug?


Thanks,
Roger
