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.
