[wp-testers] is this an error in codex, 3.0 beta, or my coding error?

Yet another solution is to put this code into a function so that you
are not setting variables within the global scope.

Something like:

function get_child_ids( $parent = 0 ) {
    $pages = get_pages( array( 'child_of' => $parent ) );
    $pageids = array();
    if ( ! empty( $pages) ) {
        foreach ($pages as $page)
            $pageids[] = $page->ID;
    }
    return $pageids;
}

echo "<pre>";
var_dump( get_child_ids(19) );
echo "</pre>";

Also just something to point out, you should generally not try to run
anything until at least the init action, not that it would have solved
anything here, just good practice.
