程序崩溃

[Luo_Bryant]

#include <windows.h>
#include <iostream.h>

DWORD WINAPI ThreadProc(
LPVOID lpParameter // thread data
);
int index = 0;
void main()
{
HANDLE hThread1;
hThread1 = CreateThread(NULL,0,ThreadProc,NULL,0,NULL);
CloseHandle(hThread1);
while(index++ < 1000)
cout<<"main thread is running"<<endl;
// Sleep(10);

// return 0;
}

DWORD WINAPI ThreadProc(
LPVOID lpParameter // thread data
)
{
while(index++ < 1000)
cout<<" thread1 is running"<<endl;
return 0;
}



这段代码运行起来有时候崩溃，有时候却又正常，这是什么情况的呀？？？
我看不出哪里有问题呀？

有可能主线程退出时，子线程还在运行 main()退出之前调用 WaitForSingleObject(hThread1, Infinite); CloseHandle(hThread1)

主线程如果退出了，子线程怎么可能还在运行？

我知道用关键段可以，我只是不明白为什么程序会崩溃而已
