call_user_func_array has slightly different behaviour in peachpie than in PHP

[noobsoftware]

call_user_func_array

public function test_fun($value=NULL, $b=false, $c=true) {
  debug::debug($value);
  debug::debug($b);
  debug::debug($c);
}

public function init_app() : void {
  $res = call_user_func_array([$this, 'test_fun'], ['test']);
}

When calling in PHP running on XAMPP this results in:

string(4) "test"
bool(false)
bool(true)

In PeachPie:

string(4) "test"

NULL

NULL

I'm using PHP 8.1 on XAMPP
