Release Status: release

Description:
        Bash process substition does not work in FreeBSD 5.2.1 where devfs(5)
        is mounted on /dev. Certain /dev/fd entries which are assumed to be
        present by bash are missing from /dev/fd.
        The same problem also exists for the bash-2.05b.007 package
        from FreeBSD 5.2.1.

Repeat-By:
        # Check that devfs(5) is mounted on /dev and execute a command
        # that uses process substitution.
        $ mount | grep devfs
        devfs on /dev (devfs, local)
        $ diff <(cat /etc/group)  <(cat /etc/group)
        diff: /dev/fd/63: No such file or directory
        diff: /dev/fd/62: No such file or directory
        $ ls /dev/fd
        0       1       2

Fix:
        Not known. As a temporary workaround I deleted the #define HAVE_DEV_FD 1
        from the generated config.h before compiling.
