Here are some known bugs to watch out for

TCP acceptor

The TCP acceptor is the ASIO data structure that accepts incoming connections, similar to accept() in c. A major bug that occurs with acceptor when it is instructed to listen on a low port like port 80. This is because regular users aren't allowed to listen on low ports. Instead of reporting the permission problem, acceptor segfaults. This is a major security issue, and means that we should be checking the user's privilege level.
