Re: request for structure documentation

A more specific question:

My code appears to be fixable by either causing the architecture specific 
unwind code to return null in frame 0, or by allowing unwind to occur here, 
but then setting the id to invalid on the unwound frame, thus preventing it 
from printing and stopping the chain of get_prev_frames.

But which is correct? This seems unclear from the comments 

thx,
