As I got "Fatal error (6)Aborted", I started the debugging
by running the first emacs under gdb.  But I found that I
can't suspend it by typing C-z once I did the step 2).
Emacs just shows this message: "Suspending an Emacs running
under X makes no sense".

This makes the debugging very difficult.  :-(
Is this a multi-tty problem?

PS.  I had to do this to get this "abort".

1) emacs -nw -Q --eval '(server-start)'
2) emacsclient -c -d :0.0
3) type C-h h
4) C-x 5 0
5) emacsclient -c -d :0.0
6) type C-h h
