Thanks for the test case.  We know what causes bugs of this form-- a
pass reports that it made progress but it actually didn't.  This
breaks a C-Reduce invariant.

If this happens often, we can put a check for this into the main
C-Reduce, but until this I hadn't seen it happen for quite a while.


Maybe it's better to add a check on this and save the temp file upon the failure? If somehow the blank transformation happened very early, then it would be quite bad.
