V8: Fatal error: CHECK(V8::ArrayBufferAllocator() != NULL) failed

[Albert Zeyer]

Hi,

I get this error when I try to run some JS code ([this](http://pastebin.com/XesBSstJ) + [this](http://pastebin.com/0VawRb16)) with V8 (tried master from two weaks ago, 3.23.17, 3.24.40, 3.25.5):

    #

    # Fatal error in ..\..\src\runtime.cc, line 785

    # CHECK(V8::ArrayBufferAllocator() != NULL) failed

    #

A lot of other JS code has worked already, so I wonder what the problem is.

It's on Win8 with a x64 build. V8 has been build just as described in the official docs (using gyp + MSVC 2012). I don't think that there was a problem because it worked fine already with most other JS code so far.

I think that there might be an issue with V8 itself, but not sure...

Some more information, including some C++ code:

Thanks,

How exactly do you run V8? Do you run d8?

No, it's some own C++ app with V8. Some stripped down example C++ code is here: http://stackoverflow.com/questions/22294854/v8-fatal-error-checkv8arraybufferallocator-null-failed

[Dmitry Lomov]

Ah, thought so. Read docs on v8::ArrayBuffer::Allocator. 

(look at Shell::Main in d8.cc for an example)

HTH,

Dmitry

[Albert Zeyer]

I'm not using ArrayBuffer in my code. I'm basically just using Script::Compile and Script::Run.

It looks like a V8 issue...

[Dmitry Lomov]

You still need to set the allocator, because V8 uses it internally, even if you do not use ArrayBuffers in your code.

[Albert Zeyer]

Ah, thanks a lot, that helped. It works now.

I wonder why it doesn't initializes such a standard allocator by default.

Also, the embedder guide should mention this. Are there maybe other things I need to init? I'm basically just doing this: https://developers.google.com/v8/get_started

Regards,

How come shell.cc doesn't set the allocator and works fine?

[Albert Zeyer]

I'm not using shell.cc. That's my own C++ app, with pure V8.
