Re: [reSIProcate] crash after receiving invalid Via line
Just add in the following check:
if (! (exists(h_Vias) && !empty(h_Vias) ...
Good find!

The stack is crashing when receiving a request with a via line equal to
"Via: ". The actual crash occurs in SipMessage.cxx:435,
SipMessage::getRFC2543TransactionId, when accessing the via header. The
header exists in the mheaders container of the SipMessage, but it does not
contain any values, so the front() call on line 435 fails.
Can some initial checking be done in the MsgHeaderScanner.cxx,
processMsgHeaderStatusLine() to drop this message?
Thanks,
