Bullet and OGRE: memory corruption problem

Post by jiandingzhe »

I previously asked this question on OGRE's forum, but some guys there let me ask the question here...

Previously, the problem is about init OGRE's config window, and construction of bullet's btCollisionDispatcher. You may see the old problem at my post on OGRE's forum:
http://www.ogre3d.org/forums/viewtopic.php?f=2&t=65497

I modified the test slightly, the memory corruption changed its place to happen. But it is still related about btCollisionDispatcher, because it won't happen if I don't new btCollisionDispatcher.

If I create the btCollisionDispatcher before initialiseAllResourceGroups, the memory corruption happens inside initialiseAllResourceGroups; if I create it after, the corruption happens inside the OIS system.

Does bullet use strange ways to manage memory??

This is the code:

Code: Select all

TestApp::TestApp():
    oPluginFile("plugins.cfg"),
    oResourceFile("resources.cfg")
{
    
    
    oRoot = new Ogre::Root(oPluginFile);
    buildResources(oResourceFile);

    if (!oRoot->restoreConfig()) throw;

    oWindow = oRoot->initialise(true, "Ogre Bullet TestApp Render Window");


    Ogre::TextureManager::getSingleton().setDefaultNumMipmaps(5);
    Ogre::ResourceGroupManager::getSingleton().initialiseAllResourceGroups();

    cout<<"#######################################"<<endl
        <<"#--- init physics world in TestApp ---#"<<endl
        <<"#######################################"<<endl;
    btConfig     = new btDefaultCollisionConfiguration();
    btDispatcher = new btCollisionDispatcher(btConfig);
//     btBroadphase = new btDbvtBroadphase();
//     btSolver     = new btSequentialImpulseConstraintSolver();

    buildOIS();

    windowResized(oWindow);
    Ogre::WindowEventUtilities::addWindowEventListener(oWindow, this);
    oRoot->addFrameListener(this);
}
and this is the error message

Code: Select all

Re: Bullet and OGRE: memory corruption problem

Post by jiandingzhe »

I occasionally found OGRE is using a customized memory allocator "nedmalloc" by default. It's possible that nedmalloc collides with the standard memory allocation. Could Bullet be configured to use different allocators, or I should let OGRE to use the standard allocator?

I've tried to configure OGRE using standard memory allocator, but the memory corruption still happens.
