You're making the same mistake I (and others) made. That of assuming that newSVrv() creates a new RV that points to the SV passed to it as an argument. It doesn't.

The documentation for the call reads:

newSVrv

Creates a new SV for the RV, rv, to point to. If rv is not an RV then it will be upgraded to one. If classname is non-null then the new SV will be blessed in the specified package. The new SV is returned and its reference count is 1.
