v8js: V8JS Segfaults with React DOM Server > 16.6.3 because of `Uint16Array`

In versions of React > 16.6.3 they start using the Uint16Array. This construct works fine when executing string; however, segfaults when creating snapshot:

use V8Js;

$jsTest = 'var newArray = new Uint16Array(15);';

$v8js = new V8Js('PHP');
$v8js->executeString($jsTest); // WORKS

$result = V8Js::createSnapshot($jsTest); // Segfaults;

Maybe this is fixed in the v8 upstream and we need a new version? Otherwise, unable to get debugging setup correct to determine more information regarding segfault.

Here is the issue I just filed with v8: https://bugs.chromium.org/p/v8/issues/detail?id=8822 PR for building with master: https://github.com/phpv8/v8js/pull/395

Previously, just instantiating and not assigning would throw the segfault: new Uint16Array(16);. That works fine on master now… but the second you try to assign it to a variable, it still segfaults. I’ll still add my PR for updating V8JS to support the latest master branch though.

Thinking it’s time to file an issue with v8.
