I've just build branches 5.4 & 5.5 with this patch on my 64-bits Debian Jessie,
no more segfault.

could you verify the fix works?
I can not reproduce segfault, but do see some warnings in valgrind, so I think
this fix should solve your problem..
thanks

Description:
------------
I was playing with the Respect data validation library from [1], which makes
use of Recursive*Iterator to retrieve validation errors.
On my 64-bits Debian Jessie, retrieving the errors with the getFullMessage()
function causes a segfault. On a 32-bits one, everything works as expected. May
be related to bug #48206.
This bug is reproducible with the versions 5.4.4-15 (packaged by Debian) and
the 5.5Git from today (bccacb6).
How to reproduce:
- Clone from [1].
- Place the attached script at the root of the checkout.
- Run # php demo.php
[1]: https://github.com/Respect/Validation
Test script:
---------------
<?php // demo.php
// Place this script at the root of the Respect\Validation library
require_once 'tests/bootstrap.php';
use Respect\Validation\Validator as v;
$userValidator = v::key('name', v::string()->length(1,32))
->key('birthdate', v::date('Y-m-d')->minimumAge(18)->setName('age'));
try {
$userValidator->assert(array('name' => 'bob', 'birthdate' => "1996-07-18"));
} catch (\InvalidArgumentException $e) {
var_dump($e->getFullMessage());
}
Expected result:
----------------
Should display:
string(73) "\-These rules must pass for "Array"
\-The age must be 18 years or more."
Actual result:
--------------
