Here’s a way to reproduce the assertion failure above (with Guile
2.0.11+):
--8<---------------cut here---------------start------------->8---
(use-modules (rnrs io ports))
(define port
(let ((input (open-input-string (make-string 1000 #\a))))
(make-custom-binary-input-port "foo"
(lambda (bv index count)
(let ((n (get-bytevector-n! input bv index
count)))
(if (eof-object? n)
0
n)))
#f #f
(lambda ()
(close-port input)))))
(setvbuf port _IONBF)
(pk 'e (port-encoding port))
(get-string-all port)
--8<---------------cut here---------------end--------------->8---
