READLINE PATCH REPORT
			   =====================

Readline-Release: 5.2
Patch-ID: readline52-002

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.
