How did it "exit normally"? did you type "C-x C-c" to exit Emacs, or
did it exit on its own?

Same question here.

This is expected: the program already exited, so its memory is no
longer accessible (it was returned to the host OS).

Doesn't happen for me.
Btw, how come your emacs.exe is in src/ directory? did you copy it
there?

This happened when I loaded tabbar.el in emacs.

Yes, I copied the compiled emacs.exe to the src/ directory, because
there is another emacs.exe in $PATH.
And I am newbie on backtracing emacs, though I have read etc/DEBUG.
Could you tell me what is the best bacetrace way when the emacs hanged ?
I will backtrace the problem in that way again.
I can reproduce the problem by switching some buffers having chinese
text repeatly.
The following flash is made in 03-15, and the problem is similar. But
the reproduction way is different now.

Are you saying that without tabbar.el it doesn't hang? If so, what is
tabbar.el? I don't see it in the CVS.

I'm still fuzzy about the specific sequence of commands that causes
hanging. Could you please show a detailed list of commands you typed
to get Emacs hang?

There's no need to copy the binary, just go to the src directory and
type something like
gdb ../bin/emacs.exe
This assumes that you have run "make install" which placed the
emacs.exe binary in the bin subdirectory of the root of the Emacs
tree.

Is the bug reproducable without --disable-font-backend?
The old font code is due to be removed soon, so there is no point in
spending too much time tracking down and fixing bugs in it now.

Famous last words... I do agree, though. Wasn't there some merge
candidate branch that should address some remaining problems?

The font-backend branch is ready to merge once Kenichi Handa finishes
writing the ChangeLogs for it. That branch does not support
--disable-font-backend and fixes several problems caused by the
compromises in the current code to support both old and new font code.

Yes, it happened only when I loaded tabbar. The previous ntemacs23 long
time ago would not hangs. I don't remember the exact date. (Maybe the
one on the ntemacs.sf.net ?)
I attached the tabbar.el file. That's not a part of cvs emacs now.

I have the following keybinding setting in .emacs file:
(global-set-key [(control \`)] 'tabbar-forward-group)
(global-set-key [(control tab)] 'tabbar-forward-tab)
(global-set-key [(shift tab)] 'tabbar-backward-tab)
The hanging is happened sometimes, when I used C-~ or C-TAB to switch
buffer which has some chinese text. Seldom C-x b.

I configured with --prefix arg, so the emacs.exe will be copied to
another directory far way from this bin subdir. I will configure without
it next time, and I can use this handy command line. :)
And how can I go back to the gdb when emacs hanged ?
I pressed C-x C-z and C-g serval times in emacs, and nothing happened.

;;; Commentary:
;;
;; This library provides the Tabbar global minor mode to display a tab
;; bar in the header line of Emacs 21 and later versions. You can use
;; the mouse to click on a tab and select it. Also, three buttons are
;; displayed on the left side of the tab bar in this order: the
;; "home", "scroll left", and "scroll right" buttons. The "home"
;; button is a general purpose button used to change something on the
;; tab bar. The scroll left and scroll right buttons are used to
;; scroll tabs horizontally. Tabs can be divided up into groups to
;; maintain several sets of tabs at the same time (see also the
;; chapter "Core" below for more details on tab grouping). Only one
;; group is displayed on the tab bar, and the "home" button, for
;; example, can be used to navigate through the different groups, to
;; show different tab bars.
;;
;; In a graphic environment, using the mouse is probably the preferred
;; way to work with the tab bar. However, you can also use the tab
;; bar when Emacs is running on a terminal, so it is possible to use
;; commands to press special buttons, or to navigate cyclically
;; through tabs.
;;
;; These commands, and default keyboard shortcuts, are provided:
;;
;; `tabbar-mode'
;; Toggle the Tabbar global minor mode. When enabled a tab bar is
;; displayed in the header line.
;;
;; `tabbar-local-mode' (C-c <C-f10>)
;; Toggle the Tabbar-Local minor mode. Provided the global minor
;; mode is turned on, the tab bar becomes local in the current
;; buffer when the local minor mode is enabled. This permits to
;; see the tab bar in a buffer where the header line is already
;; used by another mode (like `Info-mode' for example).
;;
;; `tabbar-mwheel-mode'
;; Toggle the Tabbar-Mwheel global minor mode. When enabled you
;; can use the mouse wheel to navigate through tabs of groups.
;;
;; `tabbar-press-home' (C-c <C-home>)
;; `tabbar-press-scroll-left' (C-c <C-prior>)
;; `tabbar-press-scroll-right' (C-c <C-next>)
;; Simulate a mouse-1 click on respectively the "home", "scroll
;; left", and "scroll right" buttons. A numeric prefix argument
;; value of 2, or 3, respectively simulates a mouse-2, or mouse-3
;; click.
;;
;; `tabbar-backward' (C-c <C-left>)
;; `tabbar-forward' (C-c <C-right>)
;; Are the basic commands to navigate cyclically through tabs or
;; groups of tabs. The cycle is controlled by the
;; `tabbar-cycle-scope' option. The default is to navigate
;; through all tabs across all existing groups of tabs. You can
;; change the default behavior to navigate only through the tabs
;; visible on the tab bar, or through groups of tabs only. Or use
;; the more specialized commands below.
;;
;; `tabbar-backward-tab'
;; `tabbar-forward-tab'
;; Navigate through the tabs visible on the tab bar.
;;
;; `tabbar-backward-group' (C-c <C-up>)
;; `tabbar-forward-group' (C-c <C-down>)
;; Navigate through existing groups of tabs.
;;
;;
;; Core
;; ----
;;
;; The content of the tab bar is represented by an internal data
;; structure: a tab set. A tab set is a collection (group) of tabs,
;; identified by an unique name. In a tab set, at any time, one and
;; only one tab is designated as selected within the tab set.
;;
;; A tab is a simple data structure giving the value of the tab, and a
;; reference to its tab set container. A tab value can be any Lisp
;; object. Each tab object is guaranteed to be unique.
;;
;; A tab set is displayed on the tab bar through a "view" defined by
;; the index of the leftmost tab shown. Thus, it is possible to
;; scroll the tab bar horizontally by changing the start index of the
;; tab set view.
;;
;; The visual representation of a tab bar is a list of valid
;; `header-line-format' template elements, one for each special
;; button, and for each tab found into a tab set "view". When the
;; visual representation of a tab is required, the function specified
;; in the variable `tabbar-tab-label-function' is called to obtain it.
;; The visual representation of a special button is obtained by
;; calling the function specified in `tabbar-button-label-function',
;; which is passed a button name among `home', `scroll-left', or
;; `scroll-right'. There are also options and faces to customize the
;; appearance of buttons and tabs (see the code for more details).
;;
;; When the mouse is over a tab, the function specified in
;; `tabbar-help-on-tab-function' is called, which is passed the tab
;; and should return a help string to display. When a tab is
;; selected, the function specified in `tabbar-select-tab-function' is
;; called, which is passed the tab and the event received.
;;
;; Similarly, to control the behavior of the special buttons, the
;; following variables are available, for respectively the `home',
;; `scroll-left' and `scroll-right' value of `<button>':
;;
;; `tabbar-<button>-function'
;; Function called when <button> is selected. The function is
;; passed the mouse event received.
;;
;; `tabbar-<button>-help-function'
;; Function called with no arguments to obtain a help string
;; displayed when the mouse is over <button>.
;;
;; To increase performance, each tab set automatically maintains its
;; visual representation in a cache. As far as possible, the cache is
;; used to display the tab set, and refreshed only when necessary.
;;
;; Several tab sets can be maintained at the same time. Only one is
;; displayed on the tab bar, it is obtained by calling the function
;; specified in the variable `tabbar-current-tabset-function'.
;;
;; A special tab set is maintained, that contains the list of the
;; currently selected tabs in the existing tab sets. This tab set is
;; useful to show the existing tab sets in a tab bar, and switch
;; between them easily. The function `tabbar-get-tabsets-tabset'
;; returns this special tab set.
;;
;;
;; Buffer tabs
;; -----------
;;
;; The default tab bar implementation provided displays buffers in
;; dedicated tabs. Selecting a tab, switch (mouse-1), or pop
;; (mouse-2), to the buffer it contains.
;;
;; The list of buffers put in tabs is provided by the function
;; specified in the variable `tabbar-buffer-list-function'. The
;; default function: `tabbar-buffer-list', excludes buffers whose name
;; starts with a space, when they are not visiting a file.
;;
;; Buffers are organized in groups, each one represented by a tab set.
;; A buffer can have no group, or belong to more than one group. The
;; function specified by the variable `tabbar-buffer-groups-function'
;; is called for each buffer to obtain the groups it belongs to. The
;; default function provided: `tabbar-buffer-groups' organizes buffers
;; depending on their major mode (see that function for details).
;;
;; The "home" button toggles display of buffer groups on the tab bar,
;; allowing to easily show another buffer group by clicking on the
;; associated tab.
;;
;; Known problems:
;;
;; Bug item #858306 at <http://sf.net/tracker/?group_id=79309>:
;; tabbar-mode crashes GNU Emacs 21.3 on MS-Windows 98/95.

I agree this point. But the new font backend is really slow now.

You can also do "gdb x:/path/to/emacs.exe", although it could be a
long command if the file is deep in the directory tree.

Press C-c when the window where gdb runs has focus.
If you start the Task Manager when Emacs seems to hang, does it show
that Emacs consumes lots of CPU cycles, or does it show that Emacs is
idling?

Emacs consumes lots of CPU cycles, almost the whole one of two.(Intel

Then C-c should interrupt it and "bt" should show you where it is
looping.
Btw, did you try to leave it alone for a long time, in case it's not
hung, but just takes a lot of time to do something? If not, please
do.

OK, I will backtrace in this way again.

Yes, I tried to leave it alone for about 30 minutes. Emacs continued to
consume CPU cycles.
The following is the full backtrace info. I tried to C-c, c several
times in gdb window, when emacs hung. And I found some loop info about
it. Maybe these would help.

There's a strange anomaly here: when I do the same, I only see 3
threads, not 4. And 3 is what I'd expect: there are 2 threads in a
normally running Emacs (on Windows): one thread that reads input, the
other that runs the normal Emacs code. The third thread is created by
Windows when you type C-c into the GDB window, because that's how
Windows handles SIGINT.
Please tell me when did you see the third thread, announced by this
line in GDB output:
> [New thread 3376.0xd80]
Was it when you typed C-c, or before?
Also, are you running GDB from a Command Prompt window, or in some

Oops, sorry: I forgot to tell you one important detail. After you
type C-c into the GDB window, GDB delivers SIGINT to Emacs, and that
causes Windows to start another thread (see the "New thread" message
above). When a new thread is started, GDB automatically switches to
that thread. So after typing C-c you are in the thread created by
Windows to handle SIGINT. But that thread is not the one whose
backtrace we need, which is why you see meaningless frames.
To see an interesting thread, type "thread 1" before "bt". The first
thread in the running Emacs is the one where most processing happens.
(The GDB command "info threads" will show you all the threads GDB
knows about.)

Yes, it is created when I pressed C-c. And I needed press 2 times C-c
sometimes, then I can get back to gdb. Everytime I pressed C-c, there
was a new [New thread...] created. Maybe that because I did not switch
thread 1.

I am running GDB in a normal windows command line.(win-r cmd RET)

hehe~ I am stupid. Thanks for your great patient. I will try again.
Emacs kept refreshing the tabbar's right arrow which can be pressed to
move all the tab label left. As I record in the flash show.

I'd like to remind everyone not to refer to Microsoft Windows
as "win". That is a term of praise.

And praising Windows for hanging Emacs has sort of a lynch justice
feeling to it...

"W32" is what we usually put in file names. Just "W" is a term
of disparagement nowadays in the Bush regime.

"Die Bushie!" (spelled slightly differently) means, as I learnt on the
BachoTeX conference recently, "Give me a kiss!" in Polish. It was one
of the four phrases forming the vocabulary of a participant from the UK.
You would not believe the mileage he got out of them. In particular
since two phrases were merely "Good day" and "Thank you".
