23.0.60; which-function-mode locks up emacs 23 with 100% cpu |

hi,
I noticed that if i have which-function-mode enabled in my init script
(~/.emacs) and i open any malformed python file it locks up the emacs
window with 100% cpu utilization. Python file doesn't show up on the
window and I have to cancel it by pressing C-g.
If i had desktop-save-mode enabled too and i start emacs in daemon
mode, I noticied that parent process simply waits for the child to
complete (because desktop session had this malformed python file
listed.) What is worse is, if i kill parent process using C-c, i get
my terminal back, but the child continues to eat 100% cpu in the
background :-(
I found this with couple of days old CVS tree and also with
emacs-snapshot package from http://emacs.orebokech.com/.
Malformed python file content is:
#!/usr/bin/env python
from sqlalchemy import *
from sqlalchemy.schema import *
from sqlalchemy.orm import *
class Person:
pass
mapper(Person, person_table,
class Employee:
pass
thanks,
bvk-chaitanya

This was not a bug in Python; it was a bug in end-of-defun, which was
"cleaned up" in Emacs 23. I've checked in a fix.
