Weird.  I can’t reproduce it this way:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (use-modules(srfi srfi-1))
scheme@(guile-user)> (define syms (unfold (lambda (i) (> i 1234)) (lambda (i) (string->symbol (format #f "sym~a" i))) 1+ 0))
scheme@(guile-user)> (define s (with-output-to-string (lambda () (write syms))))
scheme@(guile-user)> (equal? syms (call-with-input-string s read))
$6 = #t
--8<---------------cut here---------------end--------------->8---

Could you see if you can find a way to reproduce the problem?

Thanks,
Ludo’.
