   Are any progress made?

   Now our paper is accepted and we are modifying it according to
   referees' comments. If MIT/GNU Scheme is fixed this bug, we would like
   to mention it in our paper.

Whoops!  Thanks for reminding me.  I did make some progress on this,
but then got distracted thinking about adapting QuickCheck to Scheme
and tweaking its design.  Rather than get bogged down by that, I've
just committed a fix (in fa7ec497241664b891e2b57c8330b47e6c8ede11) and
some simple-minded tests that are good enough to catch the problem I
found.
