--- Comment #3 from Drea Pinski <pinskia at gcc dot gnu.org> ---
It could be the use of FOR_EACH_IMM_USE_FAST. I have to check if thst could
have a debug stmt or not. If so then I need to skip it.
If that is true then it is a latent bug on other branches too. Introduced by me
anyways.  Just now exposed a lot more.
