Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the [email-masked] mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. Invoke Emacs CVS top of trunk on Debian Linux "testing" built as of today (2009-01-10). Pass
the -q option.
2. Type C-h i to view the Info buffer
3. Type d to get to the top node. Insure that there is an "Emacs"
node listed.
4. Type C-s which should be bound to isearch-forward
5. Type e
6. Type m
7. Type a
8. Type c
9. Type s
10. Type :
11. It fails to find the colon character.
12. Rerun the above steps again on Emacs 22-2 and it works as
expected.
13. Back in Emacs 23, copy and paste all of the Info buffer into some
other new scrap buffer, go to the top of the buffer and repeat steps 1
through 10 and it finds the colon.

Can someone double-check that this isn't a symptom of a more serious
change of behavior in isearch or elsewhere in Emacs 23?

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'.
If you would like to further debug the crash, please read the file
/home/brentg/emacs_from_source/install/share/emacs/23.0.60/etc/DEBUG for instructions.
