Emacs command `dired-isearch-filenames-regexp' cause CPU usage 100% |

Package: Emacs
Version: 23.2.1
I use the command `dired-isearch-filenames-regexp' to find some files
in a directory. I use the the anchor `^' to match the files start with
something. Emacs is suspended and the CPU usage is 100%.Here is a
transcript:
1. Open a directory in dired mode.
2. Input `M-x dired-isearch-filenames-regexp RET ^ f RET'
Emacs will suspend rather than match the file names start with `f'.
I'm using Windows XP, Emacs version 23.2.
Bye,
Li Zhai

I installed this old patch and closed this bug.
