调用 Isolate::New() 后访问冲突执行位置 0x0000000000000000

Question

我似乎无法弄清楚启动 V8 的方法。我有这个代码：

if (!_V8Initialized)
{
    v8::V8::InitializeICU();

    v8::V8::InitializeExternalStartupData("x86\"); // (this loads ok, I checked)

    auto platform = v8::platform::CreateDefaultPlatform();
    v8::V8::InitializePlatform(platform);

    v8::V8::Initialize();

    _V8Initialized = true;
}

auto params = Isolate::CreateParams();
params.array_buffer_allocator = ArrayBuffer::Allocator::NewDefaultAllocator();
_Isolate = Isolate::New(params);

但是我得到这个错误：

Exception thrown at 0x0000000000000000 in V8.Net.Console.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

这里好像失败了:

explicit SnapshotData(const Vector<const byte> snapshot)
  : SerializedData(const_cast<byte*>(snapshot.begin()), snapshot.length()) {
    CHECK(IsSane()); <-- THIS FAILS
}

我在这里遵循了源代码（大部分）：https://chromium.googlesource.com/v8/v8/+/branch-heads/4.8/samples/hello-world.cc

...但我不确定为什么我会收到空错误。我一定是遗漏了什么...

没关系，我似乎总是在发布到 SO 后才能解决问题，大声笑。事实证明我是从 x86 目录而不是 x64 目录加载的（我应该猜到 V8_Net_Proxy_x64.dll！大声笑）。

我本来打算删除这个问题的，但我还是把它留在这里，以防其他人在半夜半睡半醒的时候陷入这个问题。 ;)
