  Log Message:
  -----------
  [OPENMP50]Do not allow several scan directives in the same parent
region.

According to OpenMP 5.0, exactly one scan directive must appear in the loop body of an enclosing worksharing-loop, worksharing-loop SIMD, or simd construct on which a reduction clause with the inscan modifier is present.
