[ncl-talk] Why the fortran routine (by WRAPIT) return the wrong value, even I did nothing with the returned variable?

[Tao Lu]

Hi Barry

Thank you for your advice.

I tried a simpler one.

What I tried:
*C NCLFORTSTART*
*      subroutine dobjanlx(grid,mlon,nlat)        *
*      implicit none*
*      integer   mlon,nlat*
*      double precision  grid(nlat,mlon) *
*C NCLEND*

*        integer   ml,nl*
*        do nl=1,nlat *
*          do ml=1,mlon *
*             grid(nl,ml) = 1.d0*
*          end do*
*        end do*

*      return*
*      end*

I called like this
    grid = new((/nlat,nlon/),double)
    grid at _FillValue = -999
    test::dobjanlx(grid,nlon,nlat)


But I got "Segmentation fault"
