Yep, it was pt_chown was missing. Fixed the issue. Now ttyp* are created with
correct ownerships.

This is definitely wrong. expect should not be calling chown(2),
it should be calling pt_chown.

Have you built the FreeBSD port or used your own build configuration?
If the latter, I suggest you build the port - it works for me.

Here is a more narrow down. This problem is happening inside a chroot jail but
only as a normal user:
Here is what it create for following command:
expect -c "spawn ls"
On FreeBSD
==
crw--w 1 test tty 0, 181 Jul 20 10:11 ttyp3
On chroot
=
crw-rw-rw- 1 root wheel 0, 181 Jul 20 10:11 ttyp3
For some reason devfs creates ttys differently.
"devfs rule showsets" shows same for both /dev and /path/dev. Its just 1, 2, 3,
4.
I tried to add a new ruleset as follows (inside chroot jail):
devfs ruleset 10
devfs rule add path tty* type tty mode 660 group tty
devfs rule applyset
Now devfs creates ttys as follows:
crw-rw 1 root tty 0, 179 Jul 20 13:08 ttyp2
So, now the question is how to get the devfs to create ttys owned by the
requested user? or can it be something else?
As for Gavin's suggestion to upgrade to Expect-5.43.0_2, actually, there is no
such version on http://expect.nist.gov/, latest is still Expect-5.43.0.

Any help will be very much appreciated. Expect's error message doesn't say anything except "something isn't working but I won't tell you what". Run truss -o truss.log -f expect -c "spawn ls" and determine which syscall is failing, with what error number, just before expect prints its "no more ptys" message. That will tell you whether it's a permissions issue, or something else. If there are no obvious errors, post a part of the log. Also, what version of expect are you running? Versions between 5.38.0_1 and 5.43.0_2 had a bug in the port Makefile that limited the number of ptys expect could see.
