I've just committed a fix for this.  The problem was due to a somewhat
sloppy use of varlist and genvar in $letrat.  For more details, please
read the commit message, which should appear at

I also fixed the problem that CRE expressions kept popping up where
they shouldn't.

So, you can eliminate the calls to `ratsimp' and `ratdisrep' which you
inserted as work-arounds in `processunits' (this would be the best
test for all this).

(By the way, shouldn't `currentdoeval' be initialized to `true' when
loading `unit.mac'?)
