try to compile and run this code: http://pastebin.com/TbLYH6kz

it'll segfault on the version shipped in arch

it worked fine before

it also works on the mentioned stable version according to http://omahaproxy.appspot.com/

arch isn't using a stable version to start with

In your example you need to add "v8::V8::Initialize()" to initialize internal V8 structures. This change comes from upstream https://github.com/v8/v8/commit/5cd10811006615e6ba5813b80d422e9c657bf004

You are right. Sorry for bothering.

I tried to check before submitting the bug. I looked for possible api breakage on Google, but only found many-many-month old messages.
