open-output-pipe problem

[Satoru Takabayashi]

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,
