[php-src] Issue #12102: Fatal error: Cannot use result of built-in function in write context

Issue: https://github.com/php/php-src/issues/12102 Author: mvorisek ### Description The following code: repro: https://3v4l.org/E8CsC ```php <?php class Cl { public static function createAnd(...$args) { var_dump($args); } public function bar() { static::createAnd(func_get_args()[0]); } } (new Cl())->bar('y'); ``` Resulted in this output: ``` Fatal error: Cannot use result of built-in function in write context ``` But I expected this output instead: ``` array(1) { [0]=> string(1) "y" } ``` the 3v4l repro shows the issue is present only in some cases, when the same code is in non-class AST, it works ### PHP Version any ### Operating System any
