[SOLVED] Some problems while executing in release mode...

Hi everyone !

I know, there are a lot of topics about why your program may not work in release mode whereas it works perfectly well in debug mode. Unfortunately, I am in this case and after several hours of reading topics, I'm asking for your help.

Here is the guilty code :

NxOgre::ShapeBlueprint* pShape = new NxOgre::CompoundShape(

		new NxOgre::CubeShape(20.0f,20.0f,20.0f, "offset: 0 0 0"),

		new NxOgre::CubeShape(1.0f,1.0f,1.0f, "offset: 0 0 0") );





// This is were the program crashes : the createBody() call

m_pMovementNode = pPhysicScene->createBody("SpaceShip;ork_rampager.mesh", pShape,

      NxOgre::Pose(Ogre::Vector3(600,100,600)), "");

This works perfectly in debug mode, as I said, but crashes systematically in release. No compilation errors and no warnings by the way.

I've verified all the pointers and variables and everything is instantiated, especially those one :

NxOgre::Scene* pPhysicScene; // well instantiated

NxOgre::Body* m_pMovementNode; // set at NULL in the constructor of the class

The release project is also linked to the resources (and to ork_rampager.mesh).
Therefore I don't really understand why this createBody() doesn't work. It may be trivial but my brain refuses to give me the answer...

Thanks a lot by advance for your ideas !

The differences are quite subtle. The major difference and probably the number on reason of crashes or unexpected behavior including yours; is in Debug mode all variables and pointers are initialized to zero. In Release it is not and most likely some random piece of memory.

Most likely it's an uninitialized pointer being treated as an initialized pointer and some piece of code is using a variable or function.

Is there any way you can trace the error in your debugger?

Thanks for your answer Betajaen.

The thing is I'm pretty sure I have initialized everything in this part of code... I also tested to "createBody" something else and somewhere else in my solution, in a part completely independent from this one, and I got the same crash when the program calls this method, in Release mode.

To trace the error, I basically print some MessageBox at strategic points to see where it crashes.

I tried to "createActor" at the exact same place with the same parameters :

NxOgre::Actor* actor = pPhysicScene->createActor(spaceShipIdentifier, pShape,

    NxOgre::Pose(Ogre::Vector3(600,100,600)), "");



m_pMovementNode = pPhysicScene->createBody(spaceShipIdentifier, pShape, NxOgre::Pose(Ogre::Vector3(600,100,600)), "");

The creation of actor works perfectly well. That makes me think it may be a "Body" problem, my variables and pointers don't seem to be guilty here.
