            * symbol.cc (gfc_get_unique_symtree): If the namespace argument
            is NULL, allocate a new symtree and provide it with the unique
            name.
            * trans-expr.cc (trans_scalar_assign): In the deep copy of a
            derived type with allocatable components, fix the rhs value if
            it is not a constant or a variable.
            * trans-stmt.cc (gfc_trans_allocate): Do not deallocate
            allocatable components of a source that is not a variable and
            is a pointer. If the DECL_NAME or its IDENTIFIER_POINTER are
            null,use gfc_get_unique_symtree with NULL namespace to obtain a
            symtree for the assignment.
