nullify after deallocation

[prasad-sawantdesai]

  ! deallocate %grid_ggd
  if (associated(struct_in%grid_ggd)) then
    do i = 1,size(struct_in%grid_ggd)
      call ids_deallocate_struct_generic_grid_ao713(struct_in%grid_ggd(i),c_data)
    enddo
    deallocate(struct_in%grid_ggd)
    nullify(struct_in%grid_ggd)  --> Added
  endif

How could I test this in my code?

[hrdoktorx]

@olivhoenen has suggested I add the nullify call in my code to see if this resolves the issue #2 . I will try.

[hrdoktorx]

I now have the following code:
250 call ids_deallocate( plasma_profiles )
251 nullify( plasma_profiles%grid_ggd )
252 call ids_deallocate( plasma_sources )
253 call ids_deallocate( plasma_transport )
254 call ids_deallocate( edge_profiles )
But I still get a segmentation fault at line 254.

I don't think this nullify is going to work. Please first reproduce in a simple case @prasad-sawantdesai.

[hrdoktorx]

In my code, nullifying all the top level AoSs from plasma_profiles, plasma_transport, and plasma_sources did not make the problem go away.

This seems like a valid addition, but it is not related to the issue, so:

• please do it in a separate PR
• and probably better to add it in a else statement from block starting line 1608 (as we test association there already)
