bool
DataChannelConnection::SendDeferredMessages()
{
  ....
  if ((result = usrsctp_sendv(mSocket, data, ...., 0) < 0)) {
  ....
}

Most likely this is what should be written here: if ((result = usrsctp_sendv(mSocket, data, ...., 0)) < 0) {

This suspicious code was found in Firefox project by PVS-Studio static code analyzer.
