                             BASH PATCH REPORT
                             =================
 
Bash-Release:   4.2
Patch-ID:       bash42-024
 
Bug-Reported-by:        Jim Avera <james_avera@yahoo.com>
Bug-Reference-ID:       <4F29E07A.80405@yahoo.com>
Bug-Reference-URL:      http://lists.gnu.org/archive/html/bug-bash/2012-02/msg00001.html
 
Bug-Description:
 
When `printf -v' is used to set an array element, the format string contains
`%b', and the corresponding argument is the empty string, the buffer used
to store the value to be assigned can be NULL, which results in NUL being
assigned to the array element.  This causes a seg fault when it's used later.
