Description:
------------
The following code gives me a segmentation fault.

Test script:
---------------
<?php
class a
{
    public $rows = array('names' => 0);

    function test()
    {
        $index = 'names';
        $amount = 1;

        $this->rows[$index] += $amount;
    }
}

$a = new a;
$a->test();

print_r($a->rows);


Expected result:
----------------
Array
(
    [names] => 1
)


Actual result:
--------------
Segmentation fault.

Program received signal SIGSEGV, Segmentation fault.

Giving your build options and platform details would be helpful.
Also a backtrace is always useful for a crash bug, see https://bugs.php.net/bugs-
generating-backtrace.php

This problem is specific to using PECL operator as indicated above.  It might be related to https://bugs.php.net/bug.php?id=64278.  I am using operator 0.4.1 plus the patch in bug 64278.  Please let me know if that helps to reproduce it.

The operator PECL package have not had a release for 4 years and development activity seems to have ceased, if a new maintainer picks up this package, then this report should be re-opened
