Crash when deallocation when using Ogre and CEGUI

[Rakkar]

Code: Select all

void CEGUIManager::Startup(Ogre::RenderWindow* window, Ogre::SceneManager* sceneManager)
{
   if (disabled)
      return;
   guiRenderer = new CEGUI::OgreCEGUIRenderer(window);
   guiRenderer->setTargetSceneManager(sceneManager);
   guiSystem = new CEGUI::System(guiRenderer);

   // TODO - don't hardcode these values once I understand all the parameters involved
   CEGUI::SchemeManager::getSingleton().loadScheme((CEGUI::utf8*)"TaharezLook.scheme");
   guiSystem->setDefaultMouseCursor((CEGUI::utf8*)"TaharezLook", (CEGUI::utf8*)"MouseArrow");
   CEGUI::MouseCursor::getSingleton().setImage("TaharezLook", "MouseMoveCursor");
   CEGUI::FontManager::getSingleton().createFont("Commonwealth-10.font");
   //guiSystem->setDefaultFont((CEGUI::utf8*)"Commonwealth-10.font");

   rootWindow=CEGUI::WindowManager::getSingleton().createWindow((CEGUI::utf8*)"DefaultWindow", (CEGUI::utf8*)"Root_Do_Not_Delete"); 
   guiSystem->setGUISheet(rootWindow);
}
void CEGUIManager::Shutdown(void)
{
   if (disabled)
      return;
   if(rootWindow)
   {
      CEGUI::WindowManager::getSingleton().destroyWindow(rootWindow);
      rootWindow=0;
   }
   if(guiSystem)
   {
      delete guiSystem;
      guiSystem = 0;
   }
   if(guiRenderer)
   {
      delete guiRenderer;
      guiRenderer = 0;
   }
}


On this line it asserts
delete guiSystem;

ogretexturemanager.cpp line 39
Expression ms_Singleton

The texture being rendered to likely needs to be removed from an active imageset before the renderer can be destroyed. You'd think the renderer destructor might handle this for you.
