BASH 4.2.45(2)-release crashes on Mac OS X 10.9.1 if PS1 contains \w

[Mario Grgic]

BASH 4.2 with patches 1-45 applied still crashes on Mac OS X 10.9.1 if PS1 
contains \w (in my case PS1="\[\033]0;\u@\h :: \w\007\]$” ).
Interestingly enough if I apply patch from 

http://lists.gnu.org/archive/html/bug-bash/2013-07/msg00011.html 

to BASH 4.2 (without any other patches applied), the crash goes away.
