FIX: On a computer that is running the .NET Framework 3.5 Service Pack 1, the JIT compiler and the Native Image Generator (Ngen.exe) that use the Mscorjit.dll file may generate incorrect code

Steps to reproduce the problem

1. Create a C++ application that is based on the .NET Framework 3.5 SP1.
2. Add a .cpp file to the project, name this file the Bug.cpp file, and then paste the following code in the Bug.cpp file.

   #using <mscorlib.dll>
   #include <stdlib.h>
   class AcGeVector3d
   {
   double x, y, z;
   public:
   __forceinline AcGeVector3d(const AcGeVector3d& src): x(src.x),y(src.y),z(src.z)
   {
   }
   __forceinline AcGeVector3d(double xx, double yy, double zz) : x(xx),y(yy),z(zz)
   {
   }
   __forceinline AcGeVector3d operator / (double val) const
   {
   return AcGeVector3d (x/val, y/val, z/val);
   }
   };
   #define GETVECTOR3D(vec3d) (*reinterpret_cast<AcGeVector3d*>(&((vec3d).m_x)))
   namespace Geometry
   {
   [System::Runtime::InteropServices::StructLayout(System::Runtime::InteropServices::LayoutKind::Sequential)]
   public value class Vector3d
   {
   internal:
   double m_x, m_y, m_z;
   Vector3d(const AcGeVector3d* obj)
   {
   GETVECTOR3D(*this) = *obj;
   }
   public:
   Vector3d(double x, double y, double z):m_x(x),m_y(y), m_z(z) {}
   Vector3d DivideBy(double value)
   {
   return Vector3d(&GETVECTOR3D(*this).operator /(value));
   }
   virtual System::String^ ToString() override
   {
   return System::String::Format("{0}, {1}, {2}", m_x, m_y, m_z);
   }
   };
   }
   

3. To compile the Bug.cpp file, run the following command:
   cl /clr /GL /O2 bug.cpp /link /dll /out:bug.dll
4. Create a new Microsoft Visual C# project to be used as the client project.
5. Name the code file the Test.cs file, and then paste the following code in the Test.cs file.

   using Geometry;
   namespace Test
   {
   class Tester
   {
   static void Main()
   {
   Vector3d v = new Vector3d(200, 200, 0);
   v = v.DivideBy(150);
   System.Console.WriteLine("{0}", v);
   }
   }
   }
   

6. To compile the Test.cs file, run the following command:
   csc /r:bug.dll test.cs
7. To embed the manifest into the Test.exe file, run the following command:
   mt.exe -nologo -manifest bug.dll.manifest -outputresource:test.exe;1
8. Run the Test.exe file.
