=dev-libs/libmemcached-1.0.18-r2 segfaults with the OPT_LIBKETAMA_COMPATIBLE enabled and a call to addServer, then resetServerList and another call to addServer. Reproducible: Always Steps to Reproduce: Example of how to reproduce in php (using pecl-memcached): <?php $host = 'localhost'; $port = '11211'; $weight = null; $m = new Memcached('test'); $m->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLE, true); var_dump($m->addServer($host, $port, $weight)); var_dump($m->resetServerList()); var_dump($m->addServer($host, $port, $weight)); var_dump($m->getServerList()); ?> Actual Results: segfault Expected Results: A call to addServer after resetServerList should not cause a segfault
