Bash Version: 3.2
Patch Level: 17
Release Status: release

Description:
        Despite man page description and assurance some years ago that
        it would be fixed
        (http://lists.gnu.org/archive/html/bug-bash/2000-11/msg00092.html),
        it appears that the bash shell option "expand_aliases" is not
        properly set for interactive shells.

Repeat-By:
        $ echo "echo \".bashrc: \`shopt expand_aliases\`\"" > ~/.bashrc
        $ echo "echo \"foo: \`shopt expand_aliases\`\"" > foo
        $ bash --version

        $ bash -i foo
        .bashrc: expand_aliases         on
        foo: expand_aliases     off
