I'm looking into it, have you tried with MES=guile SCHEME=guile?  That
would possibly give us a better backtrace :-)

It looks as if there's a typo somewhere, this

>   #<#<<record-type> <frame> (procedure)> <frame> (lambda (r) (if (#<variable 
> <> v 0) (#<variable list> (#<variable list> (#<variable list> (quote 
> #:immediate1) (#<variable -> -1 v)) (#<variable string-append> mvn____% r 
> ,$i8))) (#<variable list> (#<variable list> (#<variable list> (quote 
> #:immediate1) v) (#<variable string-append> mov____$i8,% r)))))>

suggests that the `v' passed to `armv4:value->r' is a character and not
a number.

...looking further into value->r usage

module/mescc/compile.scm
--8<---------------cut here---------------start------------->8---
        (,char (guard (char? char))
               (let ((info (allocate-register info)))
                 (append-text info (wrap-as (as info 'value->r char)))))

--8<---------------cut here---------------end--------------->8---

this one looks suspicious; could it be that you're hit by this?  Looks
like abug.

Let me know if you need more help!
