Alexandre,
i am surprised that we have gotten this far and never seen this kind of
failure.
I had actually thought that there were earlier passes that added
initialization. If that is true, then the real question is why did they fail
to make this go away earlier.
on the other hand, if there is nothing to resolve these earlier, then i guess
we need to fix it up here. But again, i am surprised that this is the first
time we have seen this problem.
