Interestingly scalar Parameters behave correctly (sorry for any line wrap issues): Wot now? cat test_par_open.f90 program test_par_opemp !$ use omp_lib implicit none integer :: kk, jx,jy,jz Integer, Parameter :: nsbcll = 27 Integer, Dimension( 1:nsbcll ), Parameter :: & nix = (/ 0, -1,-1,-1, 0, 0, 0, 1, 1, 1, -1,-1,-1, 0, 0, 1, 1, 1, -1,-1,-1, 0, 0, 0, 1, 1, 1 /) , & niy = (/ 0, -1, 0, 1,-1, 0, 1,-1, 0, 1, -1, 0, 1,-1, 1,-1, 0, 1, -1, 0, 1,-1, 0, 1,-1, 0, 1 /) , & niz = (/ 0, -1,-1,-1,-1,-1,-1,-1,-1,-1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1 /) !$omp parallel do default(none) private(kk,jx,jy,jz) do kk=1, nsbcll jx=nix(kk) jy= niy(kk) jz=niz(kk) end do !$omp end parallel do end program Wot now? ~/Downloads/gcc-4.8/bin/gfortran --version GNU Fortran (GCC) 4.8.0 20120408 (experimental) Copyright © 2012 Free Software Foundation, Inc.

This happens in 4.8.0, 4.6.2 and 4.5.2. Portland group, intel and oracle are all happy with the above code. The above code is attached, Ian
