    Description

      I had a process try to write to a QTcpSocket that had disconnected. Sure, it's my fault for trying to write to a dead socket, (A timer fired to write to a disconnected socket) but I don't think QtCore should crash the process/?
      the line of code:

      if (socket) {
    socket->write(message+"\r\n");
}

      OS Version: Mac OS X 10.14.6 (18G103)
      Exception Type: EXC_BAD_INSTRUCTION (SIGILL)
