But you're still not saying what the errors actually are. They may not 
be an indication that there is a problem with GC, but that a different 
issue has been exposed by turning on GC.

For example, you will get nuisance errors like this:

> malloc: free_garbage: garbage ptr = 0x126b5f0, has non-zero refcount 
> = 1



in the log when you open a window that uses the system template images 
that IB provides you. AFAIK this is a (harmless) bug in Leopard that 
will get fixed one of these days, and there is nothing to do in the 
meantime except ignore the messages.
