FWIW, I cannot reproduce this hear, at least not with the latest
emacs-26 branch.  I don't get the error of the first emacsclient
invocation to begin with.

Would you please use report-emacs-bug to report the problem with all
the details?  As a nice side effect, that will tell us several
important details about your system and the Emacs configuration.

Also, any reason to use -q in the daemon command?

tried report-emacs-bug, the computer doesn't have email client nor smtp,

so I still post email content here, hope it will help.

I ssh into a linux computer with root account,

then su to a normal user (#su - user, both of two ssh sessions),

start a emacs daemon, then use "emacsclient -t" to connect,

first time it will fail, in second time, the daemon will crash.

I tested with latest emacs-26 branch.

(git clone git://git.savannah.gnu.org/emacs.git --depth 1 -b emacs-26 e)

1. start emacs daemon

$ gdb -q /data/e/src/emacs

Reading symbols from /data/e/src/emacs...done.

(gdb) r -q -Q --fg-daemon

Starting program: /data/e/src/emacs -q -Q --fg-daemon

[Thread debugging using libthread_db enabled]

Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Starting Emacs daemon.

2. connect, (If I run "script /dev/null" before this, everything will work)

$ /data/e/lib-src/emacsclient -t

*ERROR*: Could not open file: /dev/pts/3

3. connect again

 /data/e/lib-src/emacsclient -t

^C

daemon crashed:
