        * trans-array.c (duplicate_allocatable): Fixed deep copy of
        allocatable components, which are liable for copy only, when
        they are allocated.
        (gfc_duplicate_allocatable): Add deep-copy code into if
        component allocated block. Needed interface change for that.
        (gfc_copy_allocatable_data): Supplying NULL_TREE for code to
        add into if-block for checking whether a component was
        allocated.
        (gfc_duplicate_allocatable_nocopy): Likewise.
        (structure_alloc_comps): Likewise.
        * trans-array.h: Likewise.
        * trans-expr.c (gfc_trans_alloc_subarray_assign): Likewise.
        * trans-openmp.c (gfc_walk_alloc_comps): Likewise.
