+                            BASH PATCH REPORT
+                            =================
+
+Bash-Release:  4.3
+Patch-ID:      bash43-009
+
+Bug-Reported-by:       Matthias Klose <doko@debian.org>
+Bug-Reference-ID:      <53346FC8.6090005@debian.org>
+Bug-Reference-URL:     http://lists.gnu.org/archive/html/bug-bash/2014-03/msg00171.html
+
+Bug-Description:
+
+There is a problem with unsigned sign extension when attempting to reallocate
+the input line when it is fewer than 3 characters long and there has been a
+history expansion.  The sign extension causes the shell to not reallocate the
+line, which results in a segmentation fault when it writes past the end.
+
+Patch (apply with `patch -p0'):
