从DLL中的静态对象构造函数调用时，std :: mutex :: try_lock挂起

Question

MSVC 2013编译器会发生这种情况。我有一个包含2个项目的解决方案：.exe和.dll。
.exe源代码：

extern "C" int test_dll();

int main() {
    test_dll();

    return 0;
}

.dll源代码：

#include <mutex>

struct AAAA {
    AAAA() {
        std::mutex mutex;
        if (mutex.try_lock()) { // always blocks
            mutex.unlock();
        }
    };

} globalObject;

extern "C" __declspec(dllexport)
int  test_dll() {
    return true;
}

try_lock来电永远不会回来。这是调用堆栈：

如果在主.exe项目中创建了全局对象，则不会发生这种情况。只有在DLL中。这里发生了什么？

MSVC2015编译器（v140工具集）不会发生挂起。
