From the Avengers.

I assumed that was because the Hulk knew it was coming. If Banner has made the decision to kill himself, then the Hulk could manifest inside of him and stop him doing it.

However, if he didn't know it was coming (and you killed him in his sleep or something) maybe that would work? This is purely speculation, though.
