bug#4183: 23.1.50; replace-string

[zwz]

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 emacs-pretest-bug@gnu.org mailing list.

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

You can reproduce the bug by
M-x replace-string RET RET
Emacs takes up the CPU and has no response.

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
d:/Program Files/Emacs/etc/DEBUG for instructions.
