Deletion of shapes

[ca$per]

Hi!
It seems that i can't delete collision shapes when exiting my app. It crashes with "Access violation reading location 0xcdcdcdc9" in btAlignedAllocator.cpp on line 198:

Code: Select all

...
  if (ptr) {
    real = *((void **)(ptr)-1);
    sFreeFunc(real);
  }
...

ptr - is 0xcdcdcdcd

Call stack:

Code: Select all

BulletMgr destructor looks like this:

Code: Select all

  for(natural i = dynamicsWorld->getNumCollisionObjects() - 1; i >= 0; i--)
    dynamicsWorld->removeCollisionObject(dynamicsWorld->getCollisionObjectArray()[i]);
  colliderList.RemoveAll(); //does not delete collider objects and just removes them from list. But tried with deletion - same results

  delete shapeList.First(); //crash here when deleting at least even one (first) shape

ColliderShape looks like this:

Code: Select all

class ColliderShape:
  public btConvexHullShape,
  public MapElement<ColliderShape>
{
  private:
    unsigned long currentKey;

  public:
    typedef unsigned long KeyType;

    ColliderShape(const char *ship, const char *collider, const float *vertices, const unsigned long count):
      btConvexHullShape(vertices, count, 12),
      currentKey(BuildColliderShapeKey(ship, collider))
    {
    };
    ~ColliderShape()
    {
    };

    const KeyType GetKey() const
    {
      return(currentKey);
    };

    static unsigned long BuildColliderShapeKey(const char *ship, const char *collider)
    {
      String<255> text = ship;
      text += collider;
      return(Text::GetTextHash(text));
    };
};

If i don't delete shapes - everything is OK, but i don't know if this is right (leaks or something?).
For this scene i have only collision objects (not rigid bodies) in it and a map of collision shapes (for caching).
World and other stuff deletion happens after shapes deletion. So it didn't happen yet.
