If you post a few lines of code, someone might spot the problem. I 
assume you are getting SS$_ACCVIO as return?
So either return_va_64 or return_length_64 wasn't passed by reference 
(or wasn't long enough but you'd have to be really
lucky to pass in a 32-bit value that sat at the very end of a page ...)
