1594              /* Array pointer.  */
1595              if (expr->expr_type == EXPR_NULL)
1596                {
1597                  dest = gfc_conv_descriptor_data (dest);
1598                  tmp = fold_convert (TREE_TYPE (se.expr),
1599                                      null_pointer_node);
1600                  gfc_add_modify_expr (&block, dest, tmp);
1601                }
1602              else

TREE_TYPE(se.expr) causes segfault since se is just initialized to zero (line 1590).
