--- Comment #5 from Michael Saboff <msaboff at apple.com> ---
A little more detail.  We are calling a function that makes a varargs tail call.  When the FTL makes a tail call and it needs to take the slow path, it doesn't properly restore the callee save registers.  Moved the restoration of callee saves to common path before deciding to take the fast or slow path.
