Hi Folks,

Finally I've found the cause of the redirection failures with perl that
I've reported some weeks ago. The problem is that perl duplicates a
stream like this:

old_h = fileno(old_stream)
old_mode = fcntl(old_h, F_GETFL)
new_stream =  fdopen(dup(old_h), mode_to_string(old_mode))

This fails because this fcntl call always returns 0, which means fdopen
is always called with "r" as the mode.

Any idea to work around this?

Thanks, Laszlo
