windbg调试std::mutex死锁问题！！！

**注意：mutex windows vista 以上系统用SRWLOCK 实现，winxp用的是rtlocks.cpp   
critical\_section  调用InterlockedCompareExchangePointer** **来实现的  一下分别以****win7  和 xp 对比下dmp**

#include "stdafx.h"
    #include "mutex_d.h"
    #include<thread>
    #include<mutex>
    #include<iostream>
    
    std::mutex test;
    
    
    
    void t_fun()
    {
    	test.lock();//重入导致死锁
    	std::cout << "hello\n";
    	test.unlock();
    }
    
    int main(int argc, TCHAR* argv[])
    {
    	test.lock();
    	std::thread th(t_fun);
    	th.join();
    
    	return 0;
    }

1、win7 系统如下图：

重点看这段代码

ntdll!NtWaitForKeyedEvent在等待一个SRWLock 所以找到死锁原因L

有没有想起 AcquireSRWLockExclusive

由于std::mutex内部实现是用SRWLock  使用的时候不能重入！！！！！
