Bug #76383 array_map on $GLOBALS returns IS_INDIRECT
Submitted: 2018-05-27 22:47 UTC Modified: -
From: bwoebi@php.net Assigned:
Status: Closed Package: Reproducible crash
PHP Version: 7.2Git-2018-05-27 (Git) OS: Irrelevant
Private report: No CVE-ID: None

Description:
------------
Since PHP 7, an array_map on $GLOBALS returns an IS_INDIRECT zval instead of a value.

Test script:
---------------
array_map(function($x) use (&$lastval) { $lastval = $x; }, $GLOBALS);

extract([], 0, $lastval); // for example, anything that will fail on an invalid type

// or for direct proof, giving unknown type
var_dump(gettype($lastval));

Expected result:
----------------
NULL // on gettype

Actual result:
--------------
Assertion failed: (0), function _convert_to_string, file /Users/Bob/php-src-X/Zend/zend_operators.c, line 585.
Abort trap: 6
