BASH PATCH REPORT

			     =================

Bash-Release: 3.2

Patch-ID: bash32-013

Bug-Reported-by: Magnus Svensson <msvensson@mysql.com>

Bug-Reference-ID: <45BDC44D.80609@mysql.com>

Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-readline/2007-01/msg00002.html

Bug-Description:

Readline neglects to reallocate the array it uses to keep track of wrapped

screen lines when increasing its size.  This will eventually result in

segmentation faults when given sufficiently long input.
