Question

背景

我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） - ＆gt; C ++库（编译器 - VS2015，OS - windows 7） - ＆gt; C库（VS 2015 - win 7） - ＆gt; C库（编译器 - gcc（minGW） - windows 10）。

我在测试虚拟机（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工作正常（Windows 7与VS 2015）。

分析

由于我无法在我的开发机器上重现这一点，我无法调试流程。我首先尝试使用GetExceptioninformation()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，它给了我跟踪堆栈跟踪： -

有人可以建议我如何解决这个问题或者可能导致这个问题的原因。
