std::thread::detach hangs in VS2013

My DLL application creates a new class in an exported function when it gets called. The class constructor creates a new thread. After calling detach() the main thread does NOT continue and the entire application hangs.

In class constructor:

spawn().detach();

private member function:

std::thread spawn() {
    return std::thread([=] { WriteProcess(false); });
}

WriteProcess:

for (;; std::this_thread::sleep_for(std::chrono::milliseconds(LOG_THREAD_TICK_RATE)))
{
    // does stuff
}

Omitting lambdas for creating a thread does not solve it.

Using CreateThread this issue does not occur and WriteProcess works as expected.

I am using VS2013 C++11 on Windows 8 and I'm currently not able to debug the process where my dll gets loaded into.
