Subject: 24.1; Startup crash in bidi init
Date: Sun, 24 Jun 2012 12:29:31 +0800

Vexing startup crash, now mysteriously healed.
Reporting it on the off chance a bidi maintainer
should glance at this and know at once what to fix.

make distclean
./configure --with-ns
make
src/emacs
### works fine in tty ###

make install
nextstep/Emacs.app
### coredumps (6 = Abort) ###

gdb nextstep/Emacs.app/Contents/MacOS/Emacs -Q
bidi_initialize (void)
...
  bidi_mirror_table = uniprop_table (intern ("mirroring"));
  if (NILP (bidi_mirror_table))
    abort ();

uniprop_table (Lisp_Object prop)
...
      result = Fload (concat2 (build_string ("international/"), table),
		      Qt, Qt, Qt, Qt);
...
      if (NILP (result))
	return Qnil;

Evidently bidi init fails to load "international/..."
perhaps due to environment, cwd, phase of moon?
Coredump goes to Apple Crash Reporter
where reload gets a running Emacs.

Maybe it finally started up because during crash report I also turned off
Apple Menu > System Preferences... > Language & Text > Input Sources > Chinese - Simplified
but now that Emacs has started once it seems to start every time
even with Chinese turned back on.

This is a duplicate of #11634.  The crashes are caused by loading
international/uni-mirrored.el from the wrong Lisp tree, one that
belongs to an older Emacs version.
