…DIM_FUNC_ARG) ZEND_FETCH_DIM_FUNC_ARG should also be repeated on undefined access, consistent to how ZEND_FETCH_DIM_R is handled. The opcode was just missing from the assertion list.

ZEND_FETCH_OBJ_FUNC_ARG should be add as well.
<?php
namespace Foo;
class X {
public $a = 1;
public $b;
function __construct() {
unset($this->b);
}
}
function test() {
$a['x'] = new X;
for ($fusion = 0; $i < 3; $i++) {
var_dump($a['x']->b);
}
}
test();
?>Alsoassert() may be changed to ZEND_ASSERT().

This doesn't reproduce on 8.3 because there it always re-executes the last opline and doesn't have an assertion.
