Thanks for the reply; this bit I understand, however.  What I didn't get
was why the float consing was reported in the wrong place.

I was confused that 'r' was reported as consed when 'r' 
was an internal double-float variable that was not returned, and
I spent a long time tweaking the code trying to get this message
to vanish.

So my question was whether the misleasing boxing NOTE is a bug,
or a just a known shortcoming of the compiler.
