System: FreeBSD crash.ilse.nl 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Thu Aug 30 18:38:55 GMT 2001 marcolz@install0.ilse.nl:/usr/src/sys/i386/compile/zlo i386
>Description:
	FreeBSD's /bin/sh cannot redirect a filedescriptor to 'itself'.
	The only problem I have encountered throught this (this is how
	I found out), is that /usr/bin/mkdep cannot write to /dev/stdout.
	This affects FreeBSD 2.2 through 5.0 current.
>How-To-Repeat:
	In /bin/sh enter:

	echo foo > /dev/fd/1

	cat < /dev/fd/0
>Fix:
	I don't know why the open on redir.c:217 fails, so I don't
	have a fix.
