Works for me on Linux, likely MacOS specific.

Description:
------------
pcntl_waitpid() always returns 0 on php 7.3 but on 7.2 it returns PID of exited child.
Example call: $pid = pcntl_waitpid($procData['pid'], $status, WNOHANG);
This is script linked below output on php 7.2.23:
```
/usr/local/Cellar/php@7.2/7.2.23/bin/php script.php
Exiting child 0
unset child 0
```
This is the output on php 7.3.10:
```
/usr/local/Cellar/php/7.3.10/bin/php script.php
Exiting child 0
```
On PHP 7.3 the script never ends and is stuck in infinite while loop because if ($res ===
$procData['pid']) expects PID to be assigned in $res on child exit but
that never happens.
Test script:
