以上core情况，只要并发高的情况下进行压力测试，多测几次必现。

[matyhtf]

请使用master分支的代码，这是因为合并 pull request #556 时，贡献者提交了一行错误代码导致的，最新的代码中已经revert了

[badxpgy]

@matyhtf 用最新的代码测了一下，现在又换另一种错误了，

SWOOLE_BASE模式的BUG，已修复。

[badxpgy]

@matyhtf
我用master 分支下载下来，重新测试了一下，这个问题还是存在。

[matyhtf]

是否make clean过，我用你的代码测试无问题。

[badxpgy]

@matyhtf
我刚刚从master分支下载全新安装，重新测了一下，还是有问题，测多几次就会重现，
用SWOOLE_PROCESS 模式就不会重现，

[matyhtf]

再抓一下core信息，看看还是onError这里报吗

[matyhtf]

测试发现是BASE模式下心跳线程把swoole_client的底层回调函数篡改了，已修复。

[badxpgy]

@matyhtf
下了最新代码，测试了很多次，现在不会重现了。
