This version is outdated and no more supported

I'm still seeing this issue on Ubuntu 14.04. Simplest way I've found to reproduce so far:

  yes | telnet some-valid-host

Crashes for me almost immediately with

  telnet: ring.cc:143: int ringbuf::flush(): Assertion `top-bot > 0 && top-bot <= count' failed.
  Aborted (core dumped)

Installed telnet version is 0.17-36build2.
