Are you trying to add a constraint attached to a null body to your space? That looks to be the cause to me.

At some point in the past, it was an undocumented "feature" that a null bodies were promoted to a static bodies. Maybe you were unknowingly taking advantage of that? With Objective-Chipmunk, you can simply create do [ChipmunkBody staticBody] to create a new static body, then assign it to something and forget about it. Objective-C will clean up the memory for you when it's done.

Just another question. I use the new ChipmunkHastySpace and objects freeze and pass the floor etc. It is very likely my old code but what is the best practice of adding objects to the space?

addPostStepCallback
add
smartAdd

What about synchronization?

Hmm. It happens with a hasty space but not with a regular space? With or without threads enabled?

So add: does a regular cpSpaceAdd*() call. It will throw an error if you attempt to do so inside of a collision callback or such. To do that, you need to schedule a post-step callback using the object to add as the key which will call your code right before the controlling cpSpace function returns (cpSpaceStep(), cpSpaceQuery*(), etc.). smartAdd: calls add: if you aren't in a callback, and schedules a post-step callback to do it if you are. Using smartAdd: all the time is a decent best practice, unless you are certain that you don't want a post-step callback scheduled. It's more relevant with smartRemove: where you know that using the object to be removed as a key will interfere with another post-step callback.

Hmm. I guess that makes a lot more questions. In all of those cases you are still creating the objects on a separate thread though? How many threads do you use? Are you creating separate threads for each object created? What exactly are the threads for?

There is really only one global shared variable in Chipmunk, cpShapeIDCounter. While it would affect determinism in a threaded environment if you wanted to do perfect replays, it shouldn't be an error for multiple shapes to have the same hashid.

What happens if you disable your use of threads entirely or is that not easily possible?
