Running on Windows 7 Pro 64-bit SP1.  Running Emacs from http://alpha.gnu.org/gnu/emacs/windows/, the latest version extracted from emacs-20111121-r106472-bin-i386.zip.

Start Emacs with runemacs -Q --no-init-file
C-x C-f foo.txt
M-x linum-mode
(Emacs doesn't crash yet)
Type anything.  Emacs instantly crashes.

Alternatively:

Start Emacs with runemacs -Q --no-init-file
C-x C-f foo.txt
Type anything
M-x linum-mode
Emacs instantly crashes.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
c:/emacs-24.0.91/etc/DEBUG.

(I am running Windows.  I have not been able to figure out how to get gdb running.  I would be glad to do it, if someone tells me how.)
