 started tor with a HashedControlPassword it segfaulted...

 Jul 19 08:47:10.000 [notice] We weren't able to find support for all of
 the TLS ciphersuites that we wanted to advertise. This won't hurt
 security, but it might make your Tor (if run as a client) more easy for
 censors to block.
 Jul 19 08:47:10.000 [notice] To correct this, use a more recent OpenSSL,
 built without disabling any secure ciphers or features.
