Redisplay crash

[Romain Francoise <romain@orebokech.com>]

Running Emacs CVS from a few hours ago, I get a segmentation fault every
time I try to enter a group in Gnus (using emacs -nw, I didn't try in
X11).  It's very reproducible.  I last updated before that in October
2004 so the bug might not be recent.

Program received signal SIGSEGV, Segmentation fault.
