Bash Version: 2.05
Patch Level: 0
Release Status: release

Description:
        When using vi-style commands (-o vi), and in a deep directory structure 
that has
        spaces in a directory name, doing a history search causes bash to crash 
with a
        segmenation fault if PS1 is set to echo pwd in the xterm titlebar and 
in prompt.

Repeat-By:

        Run this in an xterm or equivalent (I've tried it in xterm, Eterm, 
        and gnome-terminal, all with the same results)

        # PS1="\[\033]0;\u@\h:\w\007\]\h:\w # "
        # mkdir -p /thisis/aprettydeep/directory/structure/with\ some\ 
spaces/ornot
        # cd /thisis/aprettydeep/directory/structure/with\ some\ spaces/ornot
        # <esc>-k                   # enter history
        # /                         # search
