"php -e" debug with VsCode and Docker Alpine error "Segmentation fault"

[gitHusband]

1. What did you do? If possible, provides a simple script and debug step to reproduce the problem.

• 1. Start VsCode debug
• 2. Start a script php -e
• 3. Check the variables by VsCode
• 4. Sometimes if you click a variable, the debug was stopped and return error "Segmentation fault"

For example, if you click the args variable, it will return "Segmentation fault"
Current File: system/Filters/Filters.php line 163 function $this->initialize(strtolower($uri)); Of CI4 framework v4.2.4

5. What is your machine environment used (show your uname -a & php -v & gcc -v) ?

可以考虑使用 swoole-src的 xdebug分支，https://github.com/swoole/swoole-src/tree/support-xdebug
可以直接使用xdebug进行调试，前提是PHP版本要大于等于8.1
