Package: dash
Version: 0.5.12-6
Severity: normal

Please see the following test case:
# cat redir-stdout-test.sh
#!/bin/sh
set -e
rm -f /tmp/empty
true > /tmp/empty
exec 1<> /tmp/empty
ls -l /proc/$$/fd/ 1>&2
# bash redir-stdout-test.sh
total 0
lrwx------ 1 root root 64 Nov 20 05:08 0 -> /dev/pts/0
lrwx------ 1 root root 64 Nov 20 05:08 1 -> /tmp/empty
lrwx------ 1 root root 64 Nov 20 05:08 2 -> /dev/pts/0
lr-x------ 1 root root 64 Nov 20 05:08 255 -> /root/src/redir-stdout-test.sh
# dash redir-stdout-test.sh
total 0
lrwx------ 1 root root 64 Nov 20 05:07 0 -> /dev/pts/0
lrwx------ 1 root root 64 Nov 20 05:07 1 -> /dev/pts/0
lr-x------ 1 root root 64 Nov 20 05:07 10 -> /root/src/redir-stdout-test.sh
lrwx------ 1 root root 64 Nov 20 05:07 11 -> /tmp/empty
lrwx------ 1 root root 64 Nov 20 05:07 2 -> /dev/pts/0
As the test case shows, I need to redirect stdout (file descriptor 1), but
this failed in dash(1) without any warning. The same program works in bash(1)
as expected.

With further investigations, this apparent issue didn't casue real problem in
shell scripts. The newly opened bug #1056297 was the real cause.
