I think you misunderstand ... You said ...

In NSData.m I suggest to add the following
method to the class NSMutableDataMalloc:
- (void) dealloc
{
  if (bytes != 0)
    {
      NSZoneFree(zone, bytes);
      bytes = 0;
    }
  [super dealloc];
}

The dealloc method inherited by NSMutableDataMalloc already looks like 
the method above.
