C++11 std::this_thread::sleep_until() hangs when compiled with GCC 4.8.5

Consider the following program:

#include <chrono>
#include <thread>

int main() {
    std::this_thread::sleep_until(std::chrono::steady_clock::now() - std::chrono::seconds(10));

    return 0;
}

When compiled with GCC 4.8.5, it will hang. When compiled with GCC 4.9 and above or clang3.4 and above, it returns immediately,

What could cause such behavior? As I understand, GCC 4.8.5 fully supports C++11 standard.
