This ancient bug has been reintroduced in fedora: $ cat loop.sh #!/bin/bash run() { local -a A=(); local -a A=(); } while :; do run; done $ cat test2.sh #!/bin/bash $(readlink /proc/$$/exe) loop.sh & SHPID=$! sleep 1 MEM=$(ps p $SHPID o "%z" | grep -v VSZ) echo "memory consumption: $MEM" sleep 15 MEM2=$(ps p $SHPID o "%z" | grep -v VSZ) kill $SHPID echo "memory consumption: $MEM2" #compare memory consumption [ $MEM -eq $MEM2 ] $ bash test2.sh memory consumption: 130292 memory consumption: 373304 $ In both RHEL6 and RHEL7 the test passes. Version: bash-4.3.39-3.fc22 +++ This bug was initially created as a clone of Bug #126161 +++ [root@localhost root]# bash --version GNU bash, version 2.05b.0(1)-release (i386-redhat-linux-gnu) Copyright (C) 2002 Free Software Foundation, Inc. For testing purposes he uses: --------------- #!/bin/bash run() { local -a A=(); local -a A=(); } while :; do run; done --------------- This routine is eating up memory, which shows clearly in 'cat /proc/meminfo' or 'top'. --- Additional comment from Bernd Schmidt on 2004-06-16 17:31:58 EDT --- When make_local_variable finds an existing variable with the same name, it is reused. However, we never call array_dispose to free array data. This patch adds centralized freeing of all data for a reused local variable.
