在我的Windows 7 64位PC上安装Visual Studio 2013 Express后，我测试了以下简单的Hello World C ++程序：
1 #include <iostream>
2 using namespace std;
3
4 int main() {
5 cout << "Hello World" << endl;
6 return 0;
7 }
当我在正常执行中运行此代码时（使用ctr + F5），程序运行正常。但是，当我使用调试器运行它时（仅使用F5），我会看到以下消息框：
"First-chance exception at 0x778412C7 in ConsoleApplication1.exe: 0xC0000008: An invalid handle was specified.
If there is a handler for this exception, the program may be safely continued."
我按继续，然后出现另一个消息框说：
Unhandled exception at 0x778412C7 in ConsoleApplication1.exe: 0xC0000008: An invalid handle was specified.
If there is a handler for this exception, the program may be safely continued.
我再次按下继续，控制台输出如下：

所以我试图通过在第5行放置一个断点并用F10踩踏来弄清楚是怎么回事。我可以通过main（）的结束括号，然后输入一个名为“crtexe.c”的文件（参见下面的代码块）。我继续单步执行此文件，直到第＃649行突然出现异常：
645 #else /* !defined (_WINMAIN_) && defined (_CRT_APP) */
646 if ( !managedapp )
647 {
648 #ifndef _CRT_APP
649 exit(mainret);
650 #else
此行为的解释是什么？如何让它按预期工作？
