--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  David, can you have a look here?  I had a hard time following what
exactly to do with the dataflow in the uninit pass for abnormal control flow
(abnormal control flow should be considered receiving an initialized value).

Thanks.
