Bash Version: 3.1
Patch Level: 17
Release Status: release
Description:
Not sure if this is a change to how things are to be done or a
bug. I've attached my test files and original bbug1 file.
I think the ctrl-as are giving my mailer a fit so bashbug didn't
send. Sorry if I'm including the same info twice.
When creating an array and populating it with a subcommands
output there has been a change between version
2.05b.0(1) and 3.1.17(1)
such that if your subcommands generate/parse ctrl-A data
the array is not populated as before.

version 2.05b.0(1) and 3.1.17(1)

ie:

'
declare -a COM=($(echo $t | head -n1 | awk -F '{print $1,$2,$3}'))
does not work under 3.1.17(1) but does under 2.05b.0(1)
Both version works the same without the ctrl-As
ie:
t1='mhost1:10.2.2.12/10.2.2.11:TCP:0:0:0:ALIVE:2:0:0:0:0:0:0:0:0:0:10.2.2.11:10.2.2.12:1
