Re: Emacs crashes when displaying the Euro character

[Milan Zamazal]

I've got another crash, this time temporarily reproducible (and with
Emacs .gdbinit loaded before the crash).  It happens on visiting a file
containing certain characters.

GNU Emacs 22.0.50.1 (x86_64-unknown-linux-gnu, X toolkit) of 2006-08-29 on 
blackbird
