.NET Framework 3.5 SP1 bug and AutoCAD

AutoCAD and possibly other applications have the potential to be affected by a bug in newly released .NET Framework 3.5 SP1.

We get a System.ExecutionEngineError after installing the dotnet framework 3.5 SP1.
Calculations of Vector3d.MultiplyBy , Vector3d.DivideBy and Vector3d.Add are totaly wrong.

According to Autodesk this is the workaround:

Create a file called acdbmgd.ini in the AutoCAD installation directory with the following 2 lines of content:

---start of acdbmgd.ini----
[.NET Framework Debugging Control]
AllowOptimize=0
---end of acdbmgd.ini
