测试代码：

<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set('key','php redis is work');
$val = $redis->get('key');
echo $val.PHP_EOL;

go(function (){
    $redis = new \Swoole\Coroutine\Redis();
    $redis->connect('127.0.0.1', 6379);
    $redis->set('key','swoole redis work');
    $val = $redis->get('key');
    echo $val.PHP_EOL;
});

输出：
php redis is work

Segmentation fault

我用swoole的异步redis客户端也连不上。
$client = new swoole_redis; $client->connect('127.0.0.1', 6379, function (swoole_redis $client, $result) { if($result){ $client->set('key', 'swoole async redis work', function (swoole_redis $client, $result) { }); $client->get('key', function (swoole_redis $client, $result) { echo $result.PHP_EOL; }); }else { echo "swoole async redis connect fail".PHP_EOL; } });

swoole async redis connect fail

协程异常退出的原因应该是，connect没有建立，然后去关闭connect，调用了无法访问的错误内存地址。

#1585
你用最新的master分支代码试一下

[GargantuaX]

编译最新swoole要升级GCC，可能会跟项目里面的C代码有冲突，选择绕过此问题，先用PHP的普通Redis客户端，谢谢了。
