XCode 3 Debugger bug?

Hello list,
I was debugging an app of mine while I've encounter this strange thing (take
a look at screenshot). This is not the first time.

There is an NSMutableArray declared and called pdFormat.
As you can see it was allocated and inited. However I can't see into the
debugger.
Some other objects has a <value value instead the address memory.
Is this a sort of bug of xcode 3 or a mistake of mine? Is there a
workaround?
Thanks a lot
