ASIO (C++ 11) strand.post causes segmentation fault when using private member function

I'm learning to use the ASIO library and I am trying to start a custom handler after an asynchronous read.

void myConnection::start()
{
    conSocket.async_read_some(asio::buffer(conIOBuf),
        [this](const std::error_code error, std::size_t length)
        {
            std::cout << "LOG: Starting Callback\n";
            myQStrand.post(
                [this, &error]
                {
                    pushToMyQ(privateQ, error);
                });
        });
}

I've used gdb to debug the executable, however when I run it I get a segmentation fault at the pushToMyQ line in the code. I have checked both error and privateQ, they both have valid addresses and when their member functions are called they work.

myConnection is a child from a purely virtual parent class to keep the naming and some of the accessors constant between another class. privateQ is held by a manager class that passes the queue by reference to myConnection which holds it as a private member.

What could be causing the segmentation fault to happen in the lambda at the line where pushToMyQ is being executed?
