Imported from Launchpad using lp2gh.

memcached_clone(0, connection_that_already_configured_to_use_SASL_but_not_connected)
internally calls
memcached_create
that does not initialise fd field.

later SASL data fields are cloned.
that sets BINARY behaviour.
setting that behaviour tries to close existing connection (that was NOT yet made in this use-case):
memcached_behavior_set:
case MEMCACHED_BEHAVIOR_BINARY_PROTOCOL:
send_quit(ptr); // We need t shutdown all of the connections to make sure we do the correct protocol

since fd is not initialised, send_quit goes along some random fd number that happen to be in memory that was malloced during memcached_create.

trivial solution:
add
self->fd= INVALID_SOCKET;
_memcached_init in libmemcached/memcached.cc
