After the removal of that SAO parameters from the APS these are still stored in structures inside the TComAPS class. With the C-Style memory allocation from outside this creates memory leaks at the decoder because the APS contents are never disposed. Especially the parameter set manager cannot destroy these parameters because it would need a pointer to the SAO class to call the proper memory disposal methods.

All parameter storage classes should be able to destruct properly without needing pointers to function classes.
