当我使用 Visual C++ 2010 Express 的调试器运行程序 (server.exe) 时，它运行良好，但是当我将它作为 exe 运行时，它却没有；它因“Server.exe 已停止工作”对话框而崩溃。
接下来，我将 exe 重命名为“ServerInstaller.exe”并且它可以工作，所以我认为这是一个权限错误，但它不适用于管理员模式下的“Server.exe”。
然后，我将 VC++ 中的调试器附加到“Server.exe”程序，它在“free.c”中出现异常。
这个文件中的代码是
void __cdecl _free_base (void * pBlock)
{
int retval = 0;
if (pBlock == NULL)
return;
RTCCALLBACK(_RTC_Free_hook, (pBlock, 0));
retval = HeapFree(_crtheap, 0, pBlock); // Exception thrown in this function
if (retval == 0)
{
errno = _get_errno_from_oserr(GetLastError());
}
}
例外是
Server.exe 中 0x770ae3be 处的未处理异常：0xC0000005：访问冲突读取位置 0x3765f8c7。
我检查了 pBlock 的值，它是 0x007f82c0。
我的程序。
我的程序是一个RakNet服务器，刚刚成功删除了一个播放器。服务器此时正在检查来自 RakNet 的消息
