Bug description:Random segfault when using some session function

Description:
------------
The Symfony test suite makes PHP7 segfault on Travis (see
https://travis-ci.org/symfony/symfony/jobs/74375675#L1189)

On my local laptop, I can reproduce this segfault occasionally:

git clone git@github.com:symfony/symfony.git
cd symfony
composer install

then repeat the following until the segfault occurs:
php7 which phpunit --filter
LegacyDefaultCsrfProviderTest::testGenerateCsrfToken
src/Symfony/Component/Form/

There are other tests that fail from time to time, but it seems they all
use the session functions.

I'm sorry to not have a better reproducer.
