yes, I have. especially the gamma option will screw up your image in a way that may cause NANs. bit m in the bum big time on a recent show.

it's a great new node though, I just hope the polish it a bit to avoid these things

Has anyone noticed that the zDefocus adds noise into the blacks?
If you view via HSV and/or have a bounding box - you should see noise plus streaks outside of the bounding box.
They are very low values but make it into the final image.

Screen shot attached - all of this is black in source footage up to the zDefocus
