# DP: bash43-007 upstream patch
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'):
