屏蔽掉`Xdebug`试试看

`php --ri xdebug`看看xdebug详细信息，`swoole5.1`修改过一次跟xdebug有关的bug，可能是新的问题，我要看看

我没法复现这个问题，看看能不能提供一份最小化代码以供复现

@fpysky 我发现是xdebug的max_nesting_level参数设置成了512，如果是某个循环超过512次，就会抛出PHP Fatal error直接终止进程

@dhobi I found that the `max_nesting_level` parameter of xdebug is set to 512. If a certain loop exceeds 512 times, a PHP Fatal error will be thrown, terminating the process.

@dhobi @linuxd3v I don't have a good solution for xdebug. There are too many configurations for xdebug, unless we can find out through the logs which specific configuration is causing...

Do you have the xdebug extension? If so, try not using it and see.

@modrink I can not reproduce it, Is this a consistently reproducible scenario? I am directly accessing 127.0.0.1:8000 without any business logic.

@robinnydahl @modrink Perhaps some commits led to this issue.I'll take some time to test it.

@linuxd3v Can you provide a simple script for reproducing the error?
