Bash Version: 3.2
Patch Level: 39
Release Status: release

Description:

\w in PS1 prompt string confuses bash when ending in \

        The standard prompt setting in ubuntu is
PS1="${debian_chroot:+($debian_chroot)address@hidden:\w\$"

which seems harmless enough.  However, if you do

mkdir /tmp/chaos\\ ; cd /tmp/chaos\\

the prompt display hopelessly confuses bash.  At first it displays
nothing at all, then with repeated entries of RET fragments of color
ANSI sequences appear, like

address@hidden:/tmp/xxx$ mkdir /tmp/chaos\\ ; cd /tmp/chaos\\
]0;address@hidden: /tmp/address@hidden:/tmp/chaos\$ 
]0;address@hidden: /tmp/address@hidden:/tmp/chaos\$ 

Repeat-By:

See above.

Fix:

Unknown.
