                             BASH PATCH REPORT
                             =================

Bash-Release:   4.2
Patch-ID:       bash42-013

Bug-Reported-by:        Marten Wikstrom <address@hidden>
Bug-Reference-ID:       <address@hidden>
Bug-Reference-URL:      
http://lists.gnu.org/archive/html/bug-bash/2011-05/msg00049.html

Bug-Description:

An off-by-one error caused the shell to skip over CTLNUL characters,
which are used internally to mark quoted null strings.  The effect
was to have stray 0x7f characters left after expanding words like
""""""""aa.

Patch (apply with `patch -p0'):
