New description:

 The `get_pages()` function in post.php returns no results when parent !=
 0, rather than returning the pages that are children of the immediate
 page.

 Given page ID 30, which has 3 child pages, calling
 `get_pages('parent=30')` will return nothing.

 The problem is in the following lines (line ~2600 at the time of writing):

 {{{
 if ( $child_of || $hierarchical )
         $pages = & get_page_children($child_of, $pages);
 }}}

 Hierarchical, by default, is set to true, this this conditional will
 typically be true. When it does so, it filters out all of the pages
 retrieved up to this point and, by the time it returns, there are no pages
 left.

 The quick work-around I'm currently using is to call the following
 instead:
 {{{
 get_pages('parent=0&hierarchical=0');
 }}}

 overriding the default value so that conditional doesn't execute.

 The one exception to this is that calling `get_pages('parent=0')` should
 function even with this bug.
