What is /dev/pts/3?  It should name an existing terminal.

Not sure why is dumb terminal relevant here.

Anyway, AFAIK the way to do this is as follows:

 gdb ./emacs
 (gdb) tty /dev/SOMETHING
 (gdb) r -Q -t /dev/SOMETHING

(Not sure if -t /dev/SOMETHING is necessary.)

But there seems to be some bug (or feature) in Emacs: it says "emacs:
Could not open file: /dev/tty" and quits.  Other programs work as
expected with the above recipe.  Maybe some Posix guru can find out
what's wrong or how to work around that.
