+			     BASH PATCH REPORT
+			     =================
+
+Bash-Release:	4.3
+Patch-ID:	bash43-007
+
+Bug-Reported-by:	geir.hauge@gmail.com
+Bug-Reference-ID:	<20140318093650.B181C1C5B0B@gina.itea.ntnu.no>
+Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2014-03/msg00095.html
+
+Bug-Description:
+
+Using compound assignments for associative arrays like
+
+assoc=( [x]= [y]=bar )
+
+left the value corresponding to the key `x' NULL.  This caused subsequent
+lookups to interpret it as unset.
+
+Patch (apply with `patch -p0'):
