CEGUI crash when shutdown the ogre

[Caifie]

hi,every one!

i'm using ogre1.7+cegui0.7.1. i have creat a ogre app and load the interface which are dll files made by cegui. it run well except the shutdown.

when i shutdown the ogre app, i make the cegui button quit to subscribe a function quit , whose core is below:
bool quitclick(const CEGUI::EventArgs& e)
{
Ogre::Root::getSingleton().queueEndRendering();
}

when i do shutdown, the app will die at :
void SubscriberSlot::cleanup()
{
delete d_functor_impl;
d_functor_impl = 0;
}


how can i solve it, somebody help me!

Hi,

Please post your CEGUI log (or at least the indicated part of it).

What does 'crash' mean? This is meaningless drivel If you're getting some kind of unhandled exception (whether a segfault / access violation or such), or an assertion failure, please post the details and any messages that you can obtain in order that we might be able to better identify the issue.

Thanks,

CE.

thanks for your reply, CE!

infact, there aren't any useful info in the log, the log begin like below,

and end with the below line,
20/03/2010 19:15:44 (Std) ---- Begining CEGUI System destruction ----

which mean that it can not destruct successfuly.


when i run the app and shutdown it, run the

Code: Select all

FronContext::~FronContext(void)
{
   if (CEGUI::System::getSingletonPtr()) CEGUI::OgreRenderer::destroySystem();   
   if (mCameraMan) delete mCameraMan;

  //Remove ourself as a Window listener
  Ogre::WindowEventUtilities::removeWindowEventListener(mWindow, this);      

  if (mRoot) OGRE_DELETE mRoot;
}

it will die at the function,

Code: Select all

void SubscriberSlot::cleanup()
{
    delete d_functor_impl;
    d_functor_impl = 0;
}

the value of d_functor_impl is wrong.

is these enough for you ?

help me, thanks!

Thanks for the additional information, this is much more helpful since now we can see exactly where the issue is. Having said this, I can't see an exact cause. It looks like a possible double deletion issue, although I'm not 100% sure how that situation might arise.

Are you doing anything with the event subscription on the PushButton after you have subscribed it - including disconnecting, deleting anything, or any thing else?
