Sorry for the problems and thanks for looking into them.
Ken, please reread the email. The issue is *not* fixed according to
Daniel, there's still another problem. Could you look into it,
please?

I would like permission to revert zdenek's patch for a few days. There
is nothing wrong with zdenek's patch, pe se, but it excercises a part of
df that should work but does not.
We could revert my storage patch, but the problem is much deeper than
that. The storage patch only causes this problem to happen when
bootstrapping. The problem will still be there and may cause random
ices when running zdeneks code.
The problem is that when ever you delete any basic blocks, you need to
get rid of the def use and use def chains that either start or end in
the deleted block, furthermore, this has to be done before the
instructions are deleted for those blocks. This will take me a day to
get correct.
Zdenek's patch is the only code that manipulates the blocks after
use-def or def-use chains are built.
