tested with 2.2.2

(let*
  ( (ports (pipe))
    (in (car ports))
    (out (cdr ports)))
  (close in)
  (display 0 out)
  (display 1)
  (fsync out)
  (display 2))

without "(display 0 out)", error information is displayed and guile exits before "(display 2)".
with "(display 0 out)", no error information is displayed and guile exits before "(display 2)".
without "(close in)", error information is displayed in both cases.

i would expect the error information to be displayed in any case.
