[asterisk-ss7] Two libss7 questions, and, HELP!

[Matthew Fredrickson]

Are you using trunk zaptel?  If so, if you haven't updated it recently, 
I ended up introducing a bug when I was applying a bug fix that caused 
data corruption related errors such as this.  Can you update your 
zaptel to latest trunk and see if it still gives this error?  I think 
that is should fix this.
