New Comment:
I tried this after adjusting the code to be compatible with current artax:
require __DIR__ . "/vendor/autoload.php";
Amp\Loop::run(function () {
yield (new Amp\Artax\DefaultClient)->request("https://php.net/");
});
Works fine. Also tried v2, which also didn't assert. I assume this got fixed in the meantime.

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:
--------------
