Question

我正在尝试嵌入V8，但内存泄漏。以下最少的代码重现了泄漏。

int main(int argc, char* argv[])
{
    // V8 version 7.1.302.33
    v8::V8::InitializeICUDefaultLocation(argv[0]);
    v8::V8::InitializeExternalStartupData(argv[0]);
    std::unique_ptr<v8::Platform> platform = v8::platform::NewDefaultPlatform();
    v8::V8::InitializePlatform(platform.get());
    v8::V8::Initialize();

    v8::Isolate::CreateParams create_params;
    create_params.array_buffer_allocator = v8::ArrayBuffer::Allocator::NewDefaultAllocator();

    v8::Isolate* pIsolate = v8::Isolate::New(create_params); // If I remove this line and the next one, memory leak disappears
    pIsolate->Dispose();

    v8::V8::Dispose();
    v8::V8::ShutdownPlatform();
    delete create_params.array_buffer_allocator;
}

使用此代码，我的visual studio 2017在输出中打印这些泄漏

那么你知道我忘记了什么吗？

在此先感谢您的帮助；）

我复制了您的代码，并在Linux环境下运行了-fsanitize = address标志，未收到任何内存泄漏错误。
