[reSIProcate] Seg. fault in TransactionState

[Krister Jarl <kj@xxxxxxxxxxx>]

Hi!

After moving to version 1.8.5 from 1.5 we've had a couple of crashes in resiprocate. The issue seems to be a race between 200 and CANCEL. Our application constructs and sends a CANCEL down to the stack. At the same time a 200 to the INVITE is received from the wire. I can see that there has been some cleanup added to the processing of the 200 in TransactionState that I can't find in 1.5. Perhaps this is the problem?

Program terminated with signal 11, Segmentation fault.
