A monstrous Visual Studio 2010 intellisense bug

I had this happening on my development machine, (I use C# on VS2010) so I went over to The Code Project and asked if anyone else could reproduce it, and sure enough, it has been confirmed.
Steps to reproduce:

Create a new project, make it a C# console application, use all default settings. Open the generated Program.cs file and replace its contents with the following:

namespace ConsoleApplication1
{
    public class ParameterAttribute: System.Attribute
    {
    }

    class Program
    {
        [Parameter( name:"foo" )]
        int Field1;

        static void Main( string[] args )
        {
        }
    }
}



I know, there is an error in the code; please bear with me:



Move the mouse pointer over the word "name" in the code, and click. In other words, place the caret inside "name".

I hope you have saved everything, because once you do that, Visual Studio 2010 disappears without even saying good bye. It panic-quits!
