The Guix package has this patch:
'(begin
;; Work around miscompilation on Guile 3.0.0 at -O2:
;; <https://bugs.gnu.org/39251>.
(substitute* "src/md5.scm"
(("\\(define f-ash ash\\)")
"(define f-ash (@ (guile) ash))\n")
(("\\(define f-add \\+\\)")
"(define f-add (@ (guile) +))\n"))
#t)
It’s very likely that you’re hitting this problem.
HTH!
Ludo’.
