Details:

Hello,

I just experienced some wiredness with NSMapTable. NSNextMapEnumeratorPair()
seems to fail on lines #870 and 886 of NSConcreteMapTable.m (r. The
incriminated lines read:

id    k = [(NSEnumerator*)enumerator->node nextObject];

and

*value = [(NSMapTable*)enumerator->bucket objectForKey: k];

respectively. From what I gather, it doesn't make sense here to treat these
as objects ('node' in the _GSIMapEnumerator struct is a GSIMapNode structure
and 'bucket' is size_t). My own attempts at fixing this failed because I
obviously don't grok GSIMap ;-)

I hope that I've diagnosed the problem correctly. If you need any further
information, please ask.

kind regards,


Niels
