+                          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.
+
