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
#include
#include

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： 

windbg 输入~*kb打印堆栈 可以看到

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！！！！！
