Bug Description

Binary package hint: bash

When parsing e.g. the string """"a bash will incorrectly replace """" with the value 127 (0x7f).

To reproduce type echo """"a and you will se a garbage character output.

I've also reported this bug upstreams, http://lists.gnu.org/archive/html/bug-bash/2011-05/msg00049.html
