			     BASH PATCH REPORT

Patch-ID:	bash43-021

Bug-Reported-by:	Jared Yanovich <slovichon@gmail.com>
Bug-Reference-ID:	<20140625225019.GJ17044@nightderanger.psc.edu>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2014-06/msg00070.html

When the readline `revert-all-at-newline' option is set, pressing newline
when the current line is one retrieved from history results in a double free
and a segmentation fault.
