			     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'):
