Ok, thanks.  That does seem to be the one.
It was just well disguised by various operator overloads.
The actual line of code was
      avg += one_nth * v;

But * calls opMul
And the opAddAssign takes a ref so that it doesn't have to copy the
argument (which could be pretty big).

I guess I should just stick with an earlier version till we find out
if the change is permanent for D1 or not.
