Description:
------------
I got a segmentation error when I warmed up the cache in Symphony and made a typo in the property argument.
As you can see i pass 3 arguments into Annotation. But If you pass less or more named arguments into annotation or change its order - you got "Expected result".

the annotation  used as reference: https://github.com/doctrine/orm/blob/2.9.x/lib/Doctrine/ORM/Mapping/Column.php

Test script:
---------------
<?php

#[Attribute(Attribute::TARGET_PROPERTY)]
class MyAnnotation
{
    public function __construct(public bool $nullable = false) {}
}

class MyClass {
    #[MyAnnotation(name: "my_name", type: "integer", nullable: asdasdasd)]
    public $property;
}

$z = new ReflectionClass(MyClass::class);

foreach($z->getProperty("property")->getAttributes() as $attribute)
{
    $attribute->newInstance();
}

Expected result:
----------------
Fatal error: Uncaught Error: Undefined constant "asdasdasd" in index.php:18
Stack trace:
#0 index.php(18): ReflectionAttribute->newInstance()
#1 {main}
  thrown in index.php on line 18

Actual result:
--------------
zsh: segmentation fault  php index.php
