c++ - App Verifier Stop 00000900 使用文件打开对话框

问题描述

我的 C++/MFC 程序使用 CFileDialog 类来检索要打开的文件名。如果我注释掉DoModal()呼叫，则不会发生 Verifier Stops。如果打开对话框（即使它只是简单地取消），则会生成停止 - 连续三个。

所以我尝试了通用文件对话框示例：https ://github.com/Microsoft/Windows-classic-samples/tree/master/Samples/Win7Samples/winui/shell/appplatform/commonfiledialog 。同样的事情：三个 AV 900 站点。评论对的调用IFileDialog::Show()，停止消失。

注意： 根据 MFC 提供的源代码，CFileDialog 类包装了 IFileDialog；CFileDialg::DoModal()包裹IFileDialog::Show()。

我在两台计算机上复制了这个问题。第三，它运行没有问题！我强调将我的构建工具与成功机器上的工具同步——仍然可以停止。

以下是运行通用文件对话框示例的三个停止：

VERIFIER STOP 00000900: pid 0x3CB4: A heap allocation was leaked. 

    0EBA0FC0 : Address of the leaked allocation. Run !heap -p -a <address> to get additional information about the allocation.
    046E0664 : Address to the allocation stack trace. Run dps <address> to view the allocation stack.
    145C6FD8 : Address of the owner dll name. Run du <address> to read the dll name.
    55AE0000 : Base of the owner dll. Run .reload <dll_name> = <address> to reload the owner dll. Use 'lm' to get more information about the loaded and unloaded modules.

VERIFIER STOP 00000900: pid 0x3CB4: A heap allocation was leaked. 

    16289FD8 : Address of the leaked allocation. Run !heap -p -a <address> to get additional information about the allocation.
    04570E44 : Address to the allocation stack trace. Run dps <address> to view the allocation stack.
    145C6FD8 : Address of the owner dll name. Run du <address> to read the dll name.
    55AE0000 : Base of the owner dll. Run .reload <dll_name> = <address> to reload the owner dll. Use 'lm' to get more information about the loaded and unloaded modules.

VERIFIER STOP 00000900: pid 0x3CB4: A heap allocation was leaked. 

    19FC6FC0 : Address of the leaked allocation. Run !heap -p -a <address> to get additional information about the allocation.
    046E0664 : Address to the allocation stack trace. Run dps <address> to view the allocation stack.
    145C6FD8 : Address of the owner dll name. Run du <address> to read the dll name.
    55AE0000 : Base of the owner dll. Run .reload <dll_name> = <address> to reload the owner dll. Use 'lm' to get more information about the loaded and unloaded modules.

这是 DLL 名称的转储（所有三个站点都相同）：

0:000> du 145C6FD8
145c6fd8  "explorerframe.dll"

如您所见，一些地址从一站更改为下一站。

这是!heap第一个 Stop 的泄漏分配地址（参数 1）的输出：

0:000> !heap -p -a 0EBA0FC0
    address 0eba0fc0 found in
