693 results with call to new function.
694 (gfc_conv_expr): Finalize structure constructors for F2003 and
695 F2008. Warn that this feature was deleted in F2018 and, unlike
696 array constructors, is not default. Add array constructor
697 finalblock to the post block.
698 (gfc_trans_scalar_assign): Suppress finalization by setting new
699 argument in call to gfc_deallocate_alloc_comp_no_caf. Add the
700 finalization blocks to the main block.
701 (gfc_trans_arrayfunc_assign): Use gfc_assignment_finalizer_call
702 and ensure that finalization occurs after the evaluation of the
703 rhs but using the initial value for the lhs. Finalize rhs
704 function results using gfc_finalize_tree_expr.
705 (trans_class_assignment, gfc_trans_assignment_1): As previous
706 function, taking care to order evaluation, assignment and
707 finalization correctly.

717 temporaries generated in type assignment with defined
718 assignment components.
