Could you provide details how to reproduce this?

Since updating from 12-stable to 13-stable, I've found that tail(1)
crashes, reporting:
Assertion failed: (procfd > STDERR_FILENO), function service_clean, file
/usr/src/lib/libcasper/libcasper/service.c, line 394.
tail: unable to init casper: Socket is not connected
unless all three of stdin, stdout and stderr are open. Whilst it
probably doesn't make sense to call tail without stdout open. there's
no obvious reason to require that stdin or stderr must be open.
server% tail /COPYRIGHT <&-
Assertion failed: (procfd > STDERR_FILENO), function service_clean, file
/usr/src/lib/libcasper/libcasper/service.c, line 394.
tail: unable to init casper: Socket is not connected
(fixed quote with some additional tests)
I get a different error on a 13.0-RELEASE machine I converted from 12 to
current about a year ago (bash and sh):
$ tail /COPYRIGHT <&-
tail: can't limit stdio rights: Bad file descriptor
works with sudo:
$ sudo tail /COPYRIGHT <&-
* California, Berkeley and its contributors."
etc etc...
but not as root, with a different error in sh:
# tail /COPYRIGHT <&-
Missing name for redirect.
as root in bash:
# tail /COPYRIGHT <&-
tail: can't limit stdio rights: Bad file descriptor
works as both user and root in ksh
