--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
OK, so the reason is that when we actually create the parallel decl last_clique
is not yet up to its maximum since we later loop_version another loop in the
source function.  The solution is to move the last clique setting to
function outlining I guess.

Testing patch.
