Also:

4.3.30(1)-release
declare -a arr1='([0]="" [1]="")'

Debian Bug report logs: Bugs in package bash (version 4.2+dfsg-0.1+deb7u3) in

Maintainers for bash are Matthias Klose <doko@debian.org>.

You may want to refer to the following packages that are part of the same
source: bash-builtins, bash-doc, bash-static.

You might like to refer to the bash package page, to the Package Tracking
System, or to the source package src:bash's bug page.


Please do consider that it's highly likely that you won't get them to update
that for you, since that fix could break stuff, and that's the whole point of
stable, to not break things. Use a work-around, that's the sanest way.

A for loop, for example.
