--text follows this line--
This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs <at> gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Create ans edit the file "bug_file.ksh".
Try C-M-n and C-M-p over the file:
=> Unbalanced parentheses

$ cat bug_file.ksh
#!/bin/ksh

# Move point here and type C-n C-M-n C-M-n C-M-n

function foo_ok {
    case "${foo}" in
        (=G*) ;;
    esac
}

function foo_ok {
    case "${foo}" in
        "=G"*) ;;
    esac
}

function foo_bug {
    case "${foo}" in
        =G*) ;;
    esac
}

# Move point here and type C-p C-M-p
# bug_file.ksh ends here



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
/usr/share/emacs/23.3/etc/DEBUG.
