            * trans-array.c (gfc_alloc_allocatable_for_assignment): Make
            sure that class expressions are captured for dummy arguments by
            use of gfc_get_class_from_gfc_expr otherwise the wrong vptr is
            used.
            * trans-expr.c (gfc_get_class_from_gfc_expr): New function.
            (gfc_get_class_from_expr): If a constant expression is
            encountered, return NULL_TREE;
            (gfc_trans_assignment_1): Deallocate rhs allocatable components
            after passing derived type function results to class lhs.
            * trans.h : Add prototype for gfc_get_class_from_gfc_expr.
