Stable 2.0 and popen.test on Debian Squeeze

[Francis Southern <francis.southern@gmail.com>]

Hello Guilers,

As you may know, several people have been having problems with
`popen.test' with 2.0 on Debian Squeeze.  After a suggestion from
Ludovic on IRC, I tried running it with my /bin/sh symlinked to Bash
rather than Dash and there were no unexpected failures.  Yay.

Upon further inspection, the problem is that the `open-output-pipe`
test, specifically the `(pass-if "no duplicate" ...' part, fails with
Dash but not Bash.
(I was checking this by running `./check-guile popen.test'.)

Incidentally, while trying to isolate the problem further, I
discovered that loading the file from the REPL gives me:
ERROR: open-output-pipe: no duplicate - arguments: ((wrong-type-arg
"string-append" "Wrong type (expecting ~A): ~S" ("string" #f) (#f)))

And all the other tests pass.  But I don't see how this error could be
related to the shell, and indeed it happens no matter what my system
shell is set to.

Unfortunately, I'm way out of my depth here and have no idea how to
proceed.  But if there's anything you think I can do to help I'm more
than willing to oblige.


I hope this helps!
