c++ - 如何解决内存访问冲突异常

Question

背景

我已经构建了具有以下控制流程的应用程序：-

托管 C++ DLL (编译器 - VS2015, OS- windows 7) -> C++ 库 (编译器 - VS2015, OS - windows 7) -> C 库 (VS 2015 - win 7) -> C 库 (编译器 - gcc (minGW) -窗户 10）。

我在我们的测试虚拟机（带有 VS2015 运行时环境的 Windows 7）中的 C++ 库中面临访问内存冲突错误。相同的应用程序在我们的开发机器上运行良好（带有 VS 2015 的 Windows 7）。

分析

由于我无法在我的开发机器上重现这个，我无法调试流程。我首先尝试过，GetExceptioninformation()它给了我以下信息：-

Exception code: 0xc0000005
Fault offset: 0x00000000001271f0
Faulting process id: 0xedc
Faulting application start time: 0x01d3e6e36e2cbda8
Faulting application path: C:\Program Files\Microsoft Office\Office15\OUTLOOK.EXE
Faulting module path: C:\Users\Admin\AppData\Local\assembly\dl3\TMCVP0K3.2WC\VCW47EJV.PV7\26e400ac\00b47d69_f8e6d301\DarkMailEngine.DLL
Report Id: c4450271-52d6-11e8-a558-080027fa51ab

作为第二种方法，我在我的测试机器上运行了 WinDBG，它给了我以下堆栈跟踪：-

有人可以建议我如何解决这个问题或这个问题的可能原因。
