It's a problem with the test suite, not with the compiler/interpreter.

mix.scm expects the following code to error with "Heap Overflow":

   (err (make-string (quotient max-size-in-bytes-plus-1 2)))


(define max-fixnum ##max-fixnum)

(define max-fixnum-plus-1
   (let ()
     (##declare (safe) (generic))
     (+ max-fixnum 1)))

(define max-size-in-bytes-plus-1
   (let ()
     (##declare (safe) (generic))
     (quotient max-fixnum-plus-1 32)))

It does if char-size is 4, but not when it's 1.
