c++ - 调用 Isolate::New() 后执行位置 0x0000000000000000 时发生访问冲突

Question

我似乎无法弄清楚如何启动 V8。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);

但我收到此错误:

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

这里似乎失败了:

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

我在这里跟踪了源代码(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。我一定错过了一些东西......

没关系，我似乎总是在发布到 SO 后就能弄清楚事情，哈哈。事实证明，我是从 x86 目录加载的，而不是 x64 目录(鉴于 V8_Net_Proxy_x64.dll，我应该猜到!哈哈)。

我本来打算删除这个问题，但无论如何我都会把这个问题留在这里，以防其他人在半夜半睡半醒时陷入这个问题。 ;)
