Description:
------------
PHP segfaults when requesting HTTPS sites using https://github.com/amphp/artax @ ^2. I haven't been able yet to write a condensed test script.

Works fine with PHP 7.1.2RC1, but not with the current master.

Test script:
---------------
require __DIR__ . "/vendor/autoload.php";

Amp\run(function () {
    yield (new Amp\Artax\Client)->request("https://php.net/");
});'

Expected result:
----------------
No segfault.

Actual result:
--------------
php: /home/kelunik/.php-build/release/Zend/zend_hash.c:550: _zend_hash_add_or_update_i: Assertion `((ht)->gc.refcount == 1) || ((ht)->u.flags & (1<<6))' failed.
