[c-nsp] Spurious Memory Access and Traceback

[Stephen J. Wilcox]

output interpreter is pretty useful: 
https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl

in this instance it says "No matching bug was found, probably a new bug"

which it could be, ht eios is pretty new. check what memory the alignment error 
relates to, might provide a clue. 

fyi the alignment error is a memory error, the traceback isnt .. the traceback 
is showing you that a process threw an exception and is giving you the stack 
trace so that someone able to debug can work out exactly where the error 
occured.. a traceback in general could be a number of things
