Comment:

 It looks like the problem is that {{{get_pages()}}} is returning the
 incorrect pages in all exclude situations, but the page Walker orphans the
 children (so doesn't display them) in most of those cases.  In the ones
 you list above, though, the Walker does not orphan the children because
 there's no parent for it to start walking at.

 The root of the problem is {{{get_pages()}}}, since the Walker's behavior
 when fed bad data like this should probably be left undefined.

 As a workaround, you can set parent=0.
