Boost Asio tcp :: acceptor訪問衝突異常

Question

我試圖並排創建一個tcp::acceptor和libtorrent::session，但在等待來自std::cin的輸入時出現訪問衝突異常。訪問衝突發生在Boost IOCP實現中，如堆棧跟蹤所示。

• 的Windows 8.1
• MSVC 12.0（Visual Studio的2013年）
• 升壓v1.57.0
• libtorrent-rasterbar V1.0.3

一個小例子，這讓我重現該問題，

#include <boost/asio.hpp> 
#include <libtorrent/session.hpp> 

int main(int argc, char *argv[]) 
{ 
    boost::asio::io_service io_service; 
    boost::asio::ip::tcp::acceptor acceptor(io_service); 

    libtorrent::session s; 

    std::string line; 
    std::getline(std::cin, line); // <----- trigger 

    return 0; 
} 

堆棧跟蹤爲

刪除acceptor會使訪問衝突異常消失。

這是什麼原因造成的？

我遇到了同樣的問題。我通過在預處理器定義中添加BOOST_ASIO_ENABLE_CANCELIO來獲得幫助。 Here你可以找到更多信息。
