Subject: bug#17891: 24.3.92; crash with x-popup-dialog in daemon mode with enable-checking
Date: Tue, 1 Jul 2014 03:28:04 -0400 [thread overview]
Message-ID: <D59FD95B-709D-4F43-AADE-7108EF35C030@permabit.com> (raw)
Configure with --with-x-toolkit=lucid --enable-checking.
Create a .emacs file with:
(menu-bar-mode -1)
Run under X11:
emacsclient -c -n -a ""
Evaluate (e.g., in ielm):
(x-popup-dialog t '("hello"))
Emacs crashes:
#0 0x00007f4c889aaefb in raise () from /lib/x86_64-linux-gnu/libpthread.so.0

In encode_menu_string we do:
469 if (FRAME_TERMCAP_P (XFRAME (Vmenu_updating_frame)))
470 return str;
but Vmenu_updating_frame is nil.
With enable-checking, Emacs will crash; without it, it seems to quietly look at some random bit of memory and (usually?) do something that doesn't immediately cause a crash, so far.
If daemon mode isn't used to start Emacs, then menu-updating-frame will be non-nil.
If menu bar mode is left enabled (by default) then again menu-updating-frame will be non-nil.
I've run into this when clicking on a button in customize buffers caused a dialog window to be popped up.
