Yes.  The affected code hasn't been touched since 2019.  To recall, the
reproducer is this:

--8<---------------cut here---------------start------------->8---
(use-modules (srfi srfi-34)
             (srfi srfi-35))
(guard (c ((message-condition? c)
           (format #t "error: ~a~%" (condition-message c))))
  (canonicalize-path "/no/such/path"))
--8<---------------cut here---------------end--------------->8---

or this:

--8<---------------cut here---------------start------------->8---
(use-modules (srfi srfi-34)
             (srfi srfi-35))
(guard (c ((message-condition? c)
           (format #t "error: ~a~%" (condition-message c))))
  ;; This is what (canonicalize-path "/do/not/exist) ends up doing:
  (throw 'system-error "canonicalize-path" "~A" '("No such file or directory")))

error: ~A
--8<---------------cut here---------------end--------------->8---

Thanks,
Maxim
