oops.  de morgan snafu.  I must have been confused by the original form
which used inconsistent != notation :)  It used to be
!   if (current_sched_info->queue_must_finish_empty && q_size != 0)
!       abort ();
and this patch correctly implements that as
!   gcc_assert (!current_sched_info->queue_must_finish_empty || !q_size);

Fixed with the attached patch, committed as obvious

	assertification patch.
