It's an opcache optimizer problem. Wrap it in a function to reproduce:
<?php
function test() {
$a = 23;
$a = array($a);
print_r($a);
}
test();

I can't reproduce that: <https://3v4l.org/6p5r1>.
Please specify the exact version of PHP you're using, which
zend_extensions are enabled, and your OS.

Description:
------------
Redefining a variable as an array with the old value as member causes recursion.
Test script:
---------------
<?php
$a = 23;
$a = array($a);
print_r($a);
Expected result:
----------------
Array
(
[0] => 23
)
Actual result:
--------------
Array
(
[0] => Array
*RECURSION*
)
