Thanks very much for narrowing this down to a problem with `(let-values
[() (values)]) ...)'. Using that information and the small example that
you sent me, I was able to quickly find the problem, which was in an
optimizer step that drops unneeded `let-values' binding clauses. The
bug is now fixed in SVN.
