Subject: 23.0.60; OSX: server crashes on client quit when built without X toolkit
Date: Tue,  6 Jan 2009 22:27:04 +0100 (CET)

After building Emacs without X toolkit, when I do:

    $ emacs -nw -Q -f server-start

    $ emacsclient -c -e "(save-buffers-kill-terminal)"

the server crashes with the backtrace below. As previously in #581, I
cannot reproduce the problem when I comment out the call of
XrmDestroyDatabase in xterm.c. If I do that, I occasionally get:

   *ERROR*: X protocol error: BadLength (poly request too large or
    internal Xlib length error) on protocol request 7

when starting emacsclient -c, and on the next try it works again.

The full backtrace is available from:

   http://www.logic.at/prolog/btfull20090106.txt

and the regular version is:

   Program received signal EXC_BAD_ACCESS, Could not access memory.

Fixed with the following change.

2009-05-19  YAMAMOTO Mitsuharu  <mituharu <at> math.s.chiba-u.ac.jp>

	* xterm.c (x_delete_display): Don't call XrmDestroyDatabase here.
	(x_delete_terminal): Dissociate resource database from display and
	then call XrmDestroyDatabase before closing display.
