I cannot find a description of this behavior in 
http://php.net/manual/en/migration71.incompatible.php

Test script:
---------------
aim-server[~/tmp]$ cat test_class.php 
<?php

class Test {
	public $prop;

	public function main(){
		assert('self::checkCacheKey(get_object_vars($this))');
		echo 'Success';
	}
	private static function checkCacheKey($obj_properties){
		return count($obj_properties) == 1;
	}
}

$obj = new Test();

$obj->main();


Expected result:
----------------
Success output 
or 
description in 
http://php.net/manual/en/migration71.incompatible.php

Actual result:
--------------
Fatal error: Uncaught Error: Cannot access self:: when no class scope is active in /home/aim/tmp/test_class.php(7) : assert code:1

It seems the behavior has changed as of commit 6499162f[1]. Is the
reported behavior intentional, Dmitry?

Regression due to EG(scope) removal. We should assign op_array->scope in zend_eval_stringl, like we do for ZEND_INCLUDE_OR_EVAL.
