Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hello schemers,
The following program works in Guile 2.2.6 (and other R6RS
implementations), but raises an exception in Guile 2.9.7. A field called
"name" exists in record type a and record type b, but there is no actual
naming conflict as I understand it.
--8<---------------cut here---------------start------------->8---
(import (rnrs))
(define-record-type a
(fields name))
(define-record-type b
(parent a)
(fields name))
(let ((x (make-b 'a 'b)))
(write (list (a-name x)
(b-name x)))
(newline))
--8<---------------cut here---------------end--------------->8---
It should print (a b). The backtrace:
