Bug description:SIGSEGV on Symfony controller annotations

Description:
------------
We try to run a Symfony based project and have some controllers with
PHP8 annotations. But it crashes with a segmentation fault.



(gdb) run bin/console ca:c

I traced it down and the root case is this line:

https://github.com/symfony/symfony/blob/5.4/src/Symfony/Component/Routing/Loader/AnnotationClassLoader.php#L376

The constructor of
https://github.com/symfony/symfony/blob/5.4/src/Symfony/Component/Routing/Route.php#L53
is called with 

array(8) {
  [0]=>
  array(7) {
    ["path"]=>
    string(25) "/api/customer-prices/sync"
    ["name"]=>
    string(26) "api.onedrop.customerprices"
    ["requirements"]=>
    array(0) {
    }
    ["options"]=>
    array(0) {
    }
    ["defaults"]=>
    array(0) {
    }
    ["methods"]=>
    array(1) {
      [0]=>
      string(4) "POST"
    }
    ["schemes"]=>
    array(0) {
    }
  }
  [1]=>
  string(25) "/api/customer-prices/sync"
  [2]=>
  string(26) "api.onedrop.customerprices"
  [3]=>
  array(0) {
  }
  [4]=>
  array(0) {
  }
  [5]=>
  array(0) {
  }
  [6]=>
  NULL
  [7]=>
  array(1) {
    [0]=>
    string(4) "POST"
  }
}

and finishes execution and then the segmentation fault happens. So maybe
it's the yield at that point.
