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.
