/**
|
||
|
|
* Standalone driver for ChildFatalErrorGuardTest.
|
||
|
|
*
|
||
|
|
* Runs outside PHPUnit and Laravel on purpose: a real fatal error in a forked
|
||
|
|
* PHPUnit process would print the framework's console error rendering into
|
||
|
|
* the test output. Forks one child over a SocketPairIpc, lets it die in the
|
||
|
|
* requested way, and prints what the parent received as JSON.
|
||
|
|
*
|
||
|
|
* Usage: php fatal_child.php <oom|oom-disarmed|warning-then-exit|clean-exit>
