        * cp-gimplify.c (cp_gimplify_expr) <case CALL_EXPR>: For
        -fstrong-eval-order ensure CALL_EXPR_FN side-effects are evaluated
        before any arguments.  Additionally, ensure CALL_EXPR_FN that isn't
        invariant nor OBJ_TYPE_REF nor SSA_NAME is forced into a temporary.

        * g++.dg/cpp1z/eval-order5.C: New test.
