Target Milestone: ---
Invalid code affects version 6 and 7 in combination with
option -fcheck=all or -fcheck=bounds :

integer, parameter :: n = 8
integer :: i, j
real :: x(n), y(n)
x = 1.0
y = 2.0
do j = 1, 9
!$omp parallel workshare
!$omp parallel default(shared)
!$omp do
do i = 1, n
x(i) = x(i) * y(9)
end do
!$omp end do
!$omp end parallel
!$omp end parallel workshare
end do
end

end do
