Hi,
I have also seen this when using Smacc.
I found that although the problem was intermittent, I could prevent it occuring
most of the time by doing a full garbage collect before generating i.e. ...
    Smalltalk garbageCollect.

I spent some time trying to fix DependentsArray, but only made things worse. And
then I was sidetracked away from my Smacc project, and so I never did solve it.

I see that you have also posted to the main list, and I'll post some more there.
Cheers,
Andy
