bug#8157: mode related?

[Tony An]

Now, I can no longer reproduce the hung, unlike yesterday, almost every time I 
open that file to edit, it just froze there: I cannot type in anything in 
Emacs, it simply stops interact with me, and I had to bring up the Task Manager 
to kill Emacs. It's not like a prolonged delay, I waited for more than 5 
minutes one point working on other things, then came back to Emacs, it was 
still frozen there. That's why I decided to enter the bug report, since it 
happened at least 4 times yesterday. 

But today, that hung disappears, so I am not sure if this can be marked as "no 
reproducible" bug. 

I can run Emacs under GDB, although I am not sure what I am supposed to look at 
under it. 

I wasn't sure this will helps even it was hanging like yesterday because I was 
unable to do anything at all in Emacs when it was hung.  Now, it's not hanging, 
would this GDB helps to identify something unusual? 

Oh, I forgot to look at the cpu consumption yesterday when it was hung. I was 
able to working in other application normally when that happens, so I guess 
it's not that my machine is too busy at the moment...

Based on my description, if you want me to debug more with editing in the same 
file, I will be happy to. Otherwise, I am okay if you mark it as "no rep" since 
I cannot longer observe the hanging (with nothing changed, didn't even reboot 
my machine). 

Thanks.

Can you run Emacs under GDB?  If so, we could instruct you how to find out 
where it hangs (or you could read about that yourself in etc/DEBUG).

Also, are you sure it hangs, and not just does something very prolonged?  How 
much time did you wait for it to become responsive again?  Was Emacs consuming 
CPU during that time?
