efriedma added a comment.

Is FrameIndex 0 actually reliably located in a position that doesn't have an offset?  That seems unlikely to me, especially if variable-size allocation becomes involved.

Alternatively, we could fix the code that decides whether we need an emergency spill slot. But I guess there's not really much point to attempting to fold the frame indexes in the first place.
