Nvfortran: OMP directive 'simd' not allowed in pure routines

The curren nvfortran compiler (nvfortran 22.1-0 64-bit target on x86-64 Linux -tp skylake-avx512) does not allow omp simd declaration within pure subroutines, although this is explicitely allowed by the openmp standard (5.1 probably also earlier versions):

OpenMP directives, except simd and declarative directives, may not appear in pure procedures.

The following code:

module testmod
  implicit none


  pure subroutine fillup(array)
    integer, intent(out) :: array(:)

    integer :: ii

    !$omp simd
    do ii = 1, size(array)
      array(ii) = 2 * ii
    end do

  end subroutine fillup

end module testmod

triggers the compiler error mesage

NVFORTRAN-S-0155-fillup - PURE subprograms may not contain OpenMP directives (/home/aradi/omp.f90: 12)
  0 inform,   0 warnings,   1 severes, 0 fatal for fillup

when compiled with

nvfortran -c -mp ~/omp.f90

I filed TPR #31207 and sent it over to our OpenMP team.
