Did you test this on Mac OS X?  What results are returned there?

I am trying to get a handle on storage leaks and NSZoneStat()
would be ideal... except it doesn't work.

   NSZone *dftzone = NSDefaultMallocZone();
   NSZone *curzone = NSZoneFromPointer ( (void *) arglist);
   printf ("dft = %lx cur  = %lx\n",
          (long unsigned int) dftzone,
          (long unsigned int) curzone);

   struct NSZoneStats zs0 = NSZoneStats (dftzone);
   printf ("Bytes Used %d Free %d\n",
          (int) zs0.bytes_used,
          (int) zs0.bytes_free);

dft = 7ffcfdf26200 cur  = 7ffcfdf26200
