Changes (by teor):

 * keywords:   => 029-proposed memory-corruption TorCoreTeam201605
 * version:   => Tor: 0.2.7.6
 * milestone:   => Tor: 0.2.???

Comment:

 There seem to be two issues here:
 * the relay consistently produces non-ascii extrainfo content, and
 * the authorities accept non-ascii extrainfo descriptors.

 I've split the validation issue into #18938 - Authorities should reject
 non-ASCII content in ExtraInfo descriptors.

 Let's try to track down the data structure corruption in this task.
