如何在 OSX 上使用 boost asio 发送大于 256kByte 的缓冲区，在 WIN 上运行良好

Question

我有一个简单的客户端服务器方法，在 OSX 上使用 tcp 套接字和 boost asio 发送字符缓冲区。当我使用大于 256kBytes 的缓冲区时，我收到内存访问错误。这似乎发生在服务器端。但尽管如此，缓冲区大小大于 256kBytes 的完全相同的代码在 Windows 上运行得很好！

OSX 上的 gdb 告诉我

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x00000001002bebb8
[Switching to process 15955 thread 0x2003]
0x0000000100012920 in connectionThread::operator() ()

我想知道是否存在我必须注意的操作系统特定的内存分配问题。 Boost Asio 文档并没有真正的帮助。

我不想分割缓冲区！我想发送整个缓冲区，其大小最大可达 921600Bytes。它已经在带有 boost asio 的 Windows 上完美运行。

消息

char data[307200];

客户端发送消息

void send( boost::asio::ip::tcp::socket& s ) const {
    try {
        boost::asio::write( s, boost::asio::buffer( data, data_size));
    }
    catch( std::exception e ) {
        throw std::runtime_error("message send error | " + std::string( e.what() ) );
    }
}

服务器端读取消息

void read( boost::asio::ip::tcp::socket& s ) {
    try {
        // Read data
        boost::asio::read( s, boost::asio::buffer( &data, data_size ));
    }
    catch( std::exception e ) {
        throw std::runtime_error( "message read error | " + std::string( e.what() ) );
    }
}
