--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Looks like the gimplification is not handling SAVE_EXPR correctly:
    complex double val = COMPLEX_EXPR <SAVE_EXPR <__builtin_exp ((double) fun
())> * REALPART_EXPR <SAVE_EXPR <__builtin_cexpi (fun ();, 0.0)>>, SAVE_EXPR
<__builtin_exp ((double) fun ())> * IMAGPART_EXPR <SAVE_EXPR <__builtin_cexpi
(fun ();, 0.0)>>>;
