Description:
        Hello,

        I observed a memory leak when a bash array is created as a local 
variable inside a function.

        Regards,

        Rémi

        The following code (from 
http://bug-bash.gnu.narkive.com/DaBdE5P0/memory-leak-on-arrays-in-functions) 
shows this 
regression:

#!/bin/bash
run() { local -a A=(); local -a A=(); }
while :; do run; done
