Rather than deleting memory records immediately the controller has a mechanism to mark records for deletion and then actually delete them when it is safe to do so. The controller also can manage arrays of record chains.

A bug has been discovered when deleting marked records in an array of record chains when the chain is not the first element of the array. The code failed to update the proper array element. This has not been discovered until now because deleting marked records has never been done on any array with more than one element until now.

This issue has now been resolved.
