I don't fully understand all the perl calling conventions and macros, but
given that you've not manipulated the perl stack before this call_pv,
do you really need to PUTBACK? Your local stack pointer will be the same
as the global stack pointer, so isn't it always a no-op?
As to your real question, sorry, don't know. It seems most strange, and
I can't work out why it is going wrong.
