[Bug 579773] Re: telnet.netkit assert failure: telnet: ring.cc:143: int ringbuf::flush(): Assertion `top-bot > 0 && top-bot <= count' failed.

[Gregory Fong]

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.
