> When using partition regions there is a double free the ends corrupting the client process. This is caused because instead of assigning shared pointers directly the content of a shared pointer is assign to another shared pointer so the reference count is messed up. I attach a tentative fix/workaround that copies the content although the best option is possibly to create a new or modify a constructor  in VersionedCacheableObjectPartList class.
