removeCollisionObject EXC_BAD_ACCESS - Objective-C

Hello,

This is my first post here.
I'm currently trying to make a "multi-patch" plugin under Quartz Composer (Objective-C) and I'm facing a problem while removing collision objects, stored as pointer values in an NSMutableDictionary.

I create btRigidBodies with specific shape and attributes, then when I want to deallocate the dynamicsWorld I remove all rigid bodies with removeCollisionObject, but it crashes and I can't find why.

I checked every allocation / deallocation in my own program and it seems to be OK, but there I have this trouble. Here is the code. I would be extremely grateful if someone had an idea of what's happening.

Here is the dealloc method, calling a [self removeRigidBody:(btRigidBody *)body] method

Code:

- (void) dealloc{    NSArray *keys = [bodiesList allKeys];    for (int i = 0; i < [keys count]; i++) {        [self removeRigidBody:(btRigidBody *)[[bodiesList objectForKey:[keys objectAtIndex:i]] pointerValue]];       // -> pass the btRigidBody to the method    }        //delete collision shapesfor (int j = 0; j < collisionShapes.size(); j++){btCollisionShape *shape = collisionShapes[j];        delete shape;}collisionShapes.clear();        [bodiesList release];    bodiesList = nil;        [super dealloc];}

The other method :

Code:

- (void) removeRigidBody:(btRigidBody *)body{    if (body != NULL)    {        delete body->getMotionState();        delete body->getCollisionShape();    }    btWorld->removeCollisionObject(body);       // -> Here I have an EXC_BAD_ACCESS    body = NULL;    }

Thank you !
