[reSIProcate] Getting a segmentation fault in SipMessage destructor

[Vinod Kamalaraj <vkamalaraj@xxxxxxxxx>]

I have the following code, modelled after UdpTransport.cxx

    sipMsg->addBuffer(newbuf);
    
    mMsgHeaderScanner.prepareForMessage(sipMsg);
    
    char *unprocessedCharPtr;
    if (mMsgHeaderScanner.scanChunk(newbuf,
                                    len,
                                    &unprocessedCharPtr) !=
        MsgHeaderScanner::scrEnd)
        
    {
        return _RvFailure_;
    }

    Do some processing { currently commented out }

    delete sipMsg;

This works fine with a register message, but with an invite message, it
cores with the following back trace:

0xb74357c7 in raise () from /lib/tls/libc.so.6
#1  0xb743706b in abort () from /lib/tls/libc.so.6
