Comment 12 for bug 522804

Thanks.

So as you might expect from the C code, this is the
         return None, None
at the end of _process_entry, where it's deferencing everything that was in the C frame.

Re comment #8, do you need to comment out all three of those lines to make it work?

I suspect that in about line 1265-1277 a Python error is being raised and we don't notice it, therefore the variable continues set to null and we crash on the decref. I'm not sure why Pyrex isn't automatically checking.
