Freeing memory for Key itself in KeyedCollection ?

[Jae Chan Oh]

Hi,
I could only find one example for KeyedCollection type -- in SWARM GA package.

Now in the code, we have something like:

 while ( ( member = [index next]) ) {
    char* saux = calloc( 20, sizeof( char ) );
                                // Must be allocated to be used as key
    sprintf( saux, "%f", [member getPersonStrength]);
    if (! [newPplList at: (id) saux insert: member ] ) {
        [SourceMessage raiseEvent : "Something is wrong\n" ];
      }

    }
---
My question is that when I want to remove some/all members of the above 
collection, I would do something like the following:

 // now remove all members of the list
 index = [newPplList begin: [self getZone]];
 while ( ( me = [index next]) ) {
       [me drop];
       [index remove];
 }
 [index drop];
--- 
But it seems that the memory for Keys allocated using "calloc" are
not freed in the above method -- so there goes a memory leak.

What is a correct way to free to memory for KeyedCollection that also
frees the memory for Keys as well?

Thanks bunch.
