Weird... omp workshare doesn't recognize BLOCK?

program workshare
  implicit none
  integer :: i
  real :: A(5), B(5)
  B(1) = 3.344
  A = [real :: 1, 2, 3, 4, 5 ]
  !$omp parallel default(shared)
  !$omp workshare
  block
    real :: b1
    b1 = cos(b(1))
    A(:) = A(:)*cos(B1)+A(:)*cos(B1)
  end block
  !$omp end workshare nowait
  !$omp end parallel ! sync is implied here
  print *, A
end program workshare
