Description:
------------
harry@rh:/downloads]$ php test.php

Fatal error: Uncaught Error: Class 'B' not found in /mnt/data/downloads/test.php:3
Stack trace:

____________________________

[harry@rh:/downloads]$ php-opcache test.php
bla
____________________________

[harry@rh:/downloads]$ cat test.php
<?php declare(strict_types=1);

echo (new B)->test('bla'), "\n";


class B extends A
{
 public function test($input): string
 {
  return parent::test($input);
 }
}

class A
{
 public function test(string $input): string
 {
  return $input;
 }
}

Test script:
---------------
[harry@rh:/downloads]$ cat test.php
<?php declare(strict_types=1);

echo (new B)->test('bla'), "\n";


class B extends A
{
 public function test($input): string
 {
  return parent::test($input);
 }
}

class A
{
 public function test(string $input): string
 {
  return $input;
 }
}

Expected result:
----------------
this is a major bug - the class at bottom defined in the same file is explected to be found without opcache loaded

[harry@rh:/downloads]$ which php
/usr/bin/php

[harry@rh:/downloads]$ which php-opcache
alias php-opcache='/usr/bin/php -d "zend_extension=opcache.so" -d "opcache.enable_cli=1"'
        /usr/bin/php

Actual result:
--------------
class only found when opcache is loaded
