No, sorry if I was unclear.  From what I see the gdb session is not  
started in the Emacs src directory.  Do something like this:

% cd emacs/src
% gdb emacs
...
Breakpoint 1 at 0x814814c: file emacs.c, line 461.
Breakpoint 2 at 0x811bf10: file xterm.c, line 7795.
(gdb)


The last two lines indicate that the breakpoints in .gdbinit has been  
set correctly.  Then just run emacs:
(gdb) r

and call (x-synchronize t) in Emacs (it will make Emacs much slower).

When the breakpoint in x_error_quitter is hit, then do a stack trace.
You can also step a couple of times in x_error_quitter (n command in  
gdb) until you come to this line:

      x_connection_closed (display, buf1);

There you just
(gdb) p buf1

so we can see that it is the same error.
