Question

This may sound like a noob question, because it is. I have tried for days to figure out what I am doing to make it crash, but I can’t figure it out.

I have various objects that use CCActions. When the objects need to be removed from screen, I call [spriteObject stopAllActions]; I then release the actions. (I retain the actions in init, as I was trying to avoid this kind of crash).

The program randomly crashes at this line in CCScheduler:

[elt->currentTimer release];

The error message is that I am sending a message to a deallocated instance. But I can’t figure out what gets deallocated when. I retain all the actions I create. I even tried running the program without ever releasing the actions, to see If that was the cause, but it still crashes.

Sometimes it crashes after 20minutes, sometimes after 2 minutes. It is pretty random.
I’m not sure what to put up because the code is pretty spread out.

Basically, I have a Sprite, which contains a “Strategy” object, which contains the CCAction that is running. At run time I create a “strategy” and pass it to the sprite which retains the strategy.

The sprites are not deallocated until the end of program execution.

Any ideas on how I can figure out what is being deallocated, where and why? I really can’t figure it out. Not sure what information to put up here. :C

Cocos2d is currently not thread safe, and the api’s are not expected to be called from other threads.
