This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
Please describe as succinctly as possible:
- What happened.
- What you thought should have happened.
- Precisely what you were doing at the time.
Please also include any C or lisp back-traces that you may have.

Vin,
It is almost certainly a bug, at least in my installation.
With "binary search" I found the treshold of the selection
size at which the selection killing fails: 262040 characters.
When the selection is <= 262040 characters, the killing with
C-w happens *instantaneously*. When it is >= 262041, it never
happens, and all the memory is eaten.
Can someone confirm/deny that under a different instalation/environment?
Again, it is xemacs 21.4.4, Linux.
Huh! You are right, Minko - Something is seriously broken. On my
Linux box at home, I'm seeing the same behavior. Here's the recipe to
reproduce:
1. xemacs -vanilla
2. C-x C-f bigfile
3. C-u 262050 C-f
4. M-<
5. C-x C-x
6. C-w
This does not happen when I'm running xemacs -nw, by the way.
When I'm running under gdb, here's the backtrace I generate after
interrupting the process:
