This could have been the case as I was messing around in the repl. However when
I tried to find the simplest case to replicate
the error I restarted scheme, did a load, then got the error. Then I restarted
again, pasted the code from the file to *scheme*
where everything was OK. Another thing tha

There is this "gotcha" with t
This is the scmutils generic ref. When I replace the generic ref with
vector-ref it works ok, I just thought this error was strange, the only

I’m using ScmUtils 2016 compiled to a band using version 9.2 on OSX, and I’m
running into a strange error.
The simplest case I can boil it down to is:
Using *scheme* I can do
(define (g2d x y v)
(* (ref v 0) (exp (- (+ (/ (square (- x (ref v 1))) (* 2 (square (ref v 3))
)) (/ (square (- y (re
