Hi!
I tried guile 1.4.1 and found a problem on open-output-pipe.
% cat x.scm
(use-modules (ice-9 popen))
(let ((port (open-output-pipe "tr a-z A-Z")))
(write-line "abc123" port)
(close-pipe port))
With guile 1.3.4, it works fine.
% /usr/bin/guile -s x.scm # guile 1.3.4
ABC123
%
Hoever, with guile 1.4.1, it doesn't produce any outputs.
% /usr/local/bin/guile -s x.scm # guile 1.4.1
%
Thanks,
